Slow system and application startup times

Hi,
I've got a 17" Macook Pro (Early 2011) 2.2 GHz Intel Core i7 - ever since I bought it I feel like it runs a little slow.
I've been a long-time mac used but I feel a little disappointed with this machine.
e.g.: Startup time takes around 4 minutes.
Applications take around 10 seconds to start.
Chrome sometimes takes 5-10 seconds to start, about the same to quit.
My Xbench scores fluctuate wildly - best I've ever got is 220, worst is 18. 160 is about the average.

http://db.xbench.com/merge.xhtml?doc2=537725
http://db.xbench.com/merge.xhtml?doc2=544252
I feel that tried everything including:
- Creating a new user
- Repairing disk permissions
- DIsk verify and repair
- Removing all startup items
- Installing extra ram (currently at 8GB)
It runs well most of the time but frustratingly slow sometimes and there doesn't seem to be any anomalous activity in activity monitor. I feel that it could be the hard disk, but don't know (I always have 250-350gb free).
Any help appreciated!

Thanks for the link. I've never seen that page before but I have done everything in that list.
It's not a spinning beachball issue - the system doesn't lock-up often it just takes a **** long time to do some things. I didn't really realise it as a problem until I started using other people's older/lower spec'ed macs and noticed that they run FASTER than mine.
Activity monitor pics - just after a restart with my usual apps running:
CPU https://skitch.com/e-hellodaniel/83pq5/activity-monitor
Memory https://skitch.com/e-hellodaniel/83pq7/activity-monitor
Disk https://skitch.com/e-hellodaniel/83pxg/activity-monitor
Even using Skitch to take those screenshots took ages.
It's almost like the disk or CPU is throttled back or bottlenecked, and always has been...

Slow system and applications.

Hello everybody!
I have macbook pro which I bought 8 months ago and I have a mac universal which I bought 5 years ago. I usually use my macbooks for online research, pages, keynote and numbers. Besides that I dont do something special. But lately both my macbooks are running very slow and most of the time I have pop-ups on the safari or on firefox. I have an application which name is mackeeper to speed up my both macbook but It seems like it doesnt do anything. I am trying to learn more about macbook. What kind of applications that I have to use for speed up for my macbooks? Or what should I do? Please let me know I would like to learn more about Mac.
(my both macbooks are up to date)
Thank you so much!

Hi Dibenkorn, first of all thank you so much for your time!! this report belongs to my macbook universal one! I dont have the BBM application but I believe I still have its root under my data! What should I do? How I can delete all those 3rd party links!!!

Slow system and odd startup icon

If I'd only changed one variable at a time then I'd probably not be asking this question... but since I changed so many here goes:
About the same time as upgraded to 10.4.8 I added a third internal drive (first one in the slower drive area near the front of my MDD G4) and installed the newest iLife suite.
My system has slowed down amazingly... just trying to activate Finder to look at a file list, changing an active selection from Mail to Safari, opening most any app... causes a 5 to 10 second spinning beach ball.
My only clue is a momentarily new symbol when I restart the CPU: Prior to the launching of the normal Apple screen I see a small folder that alternates with a question mark for just a second or two. Then startup proceeds normally. I thought that icon was for a problem finding the startup drive, but I've not changed where the system resides or that drive at all.
Any thoughts would be greatly appreciated,
Pat

Did you also update your iLife apps and QuickTime? And did you repair permissions? Two things to do to see if you can find the source of the slow down:
1. Create a test user using System Preferences->Accounts. Leave the test user basically as it is created, don't add contextual menus, menu extras, fonts, nothing extra. Try logging into the test user and see if the responsiveness is back to normal. If so the problem is something in your usual account rather than a system level problem.
2. Try launching Console from your utilities folder and leave it running in the background. Are you getting any odd error messages?
Also check to see if the drives are set to sleep when possible, make sure the check box is UNchecked in System Prefs->Energy Saver. Usually though the slow down when that is checked is intermittant rather than constant.

MVC model in Web systems and applications

MVC model in Web systems and applications
Object-oriented design model is experience, MVC idea is a user interface for the original. This article discusses how the major application areas in the new Web design patterns and the use of MVC framework. The article first introduced the concept of design patterns and characteristics, and MVC architecture design concepts and analysis of the MVC framework contains several key models. Based on the characteristics of Web applications on how to use patterns and MVC framework made some design ideas.??
1. Introduction
1.1 design model
Object-oriented technology and the emergence of software applications has greatly enhanced the trusted and software quality. Object-oriented programming than previous models to various programming simple and efficient, but the object-oriented design methodology than the previous design methods to complex and much more skill, a good design should be both on the issue of gender, but also to take full account of the problems and needs sufficient interoperability. In the past 10 years, people in the object-oriented technology and the practical application of research to explore certain issues in relation to the creation of a number of good solutions, the so-called object-oriented design patterns. Object-oriented technology is one of the purposes of enhancing the software trusted, and to design model, design programmes in important positions from a deeper sense of meaning and essence embodies trusted. There are many people in the design model definition, which cited Christopher Alexander is the largest design model definition : Each design model is a tripartite rule, which expresses a contextual environment (Context), a problem and a solution. Design models generally following basic elements : model name, the purpose solution effect 1995-1998 code and related design models. There are several classifications design patterns can be divided into a model based on the purpose (Creational), structural type (Structural) and the type of behaviour (Behavioral) three. It is mainly used in the creation of a model-based object model-based structure to deal primarily with the category or combination of objects, used to describe behavior-based model is the main target for the category or how stress and how to allocate responsibilities. Design patterns can be divided into categories based on the scope and target mode model type model dealing with the relationship between the categories and sub-categories, these relations through the establishment of succession in Translation moment to be finalized, are static. Model is targeted at addressing the relationship between the moment of change these relations in the operation, more dynamic. Model features : through the experience acquired in a structured format to write down, avoid encountering the same problems on the first design, exist in different abstract level, in continuous improvement, can be trusted artificial product for the design and best practice in the world to be combined to address larger issues.
1.2 MVC framework
MVC was first used in a user interface Smalltalk-80 China. M representative models Model, representatives maps View V, C representatives controller Controller. MVC trusted code with the aim of increasing the rate of data reduction expressed, the data describing the operation and application coupled degrees. Also makes software Keweihuxing, restorative, expansionary, flexibility and packaging of greatly enhanced. Single-user applications are usually incident-driven user interface to the organizational structure. Staff development tool with an interface painting of a user interface interface code based on user input and then prepare to implement the corresponding moves, many interactive development environment encouraged to do so, because it emphasizes first and then a functional interface. Some software design model is the strategy that will be fixed before the code into the regular system of the final. Result is that the procedures and organizations around the user interface elements in the user interface elements of those moves, data storage, applications and functions of the code is used to indicate the way intertwined. In single-user system code structure can be so, because the system will not demand frequent changes. But for a large system such as large Web systems, or e-commerce systems to be applied. Model by incorporating data from a variety of access and control data can be separated to improve distributed system design. MVC design pattern is composed of three parts. Model is the application object, no user interface. Type in the screen showing that it represents the flow of data users. Controller user interface definition response to user input, the users responsible for the action against the Model into operation. Model View data updated to reflect the adoption of data changes.
2. MVC design pattern,
An MVC framework for the design of the system includes many models, but with MVC is most closely related to the following three models : Observer, Cambridge and Strategy.
2.1 Observer models
MVC through the use of purchase / notification form and the separation of the Model View. View to ensure that their content accurately reflected Model and state. Once Model content changes, there must be a mechanism to allow notification to the relevant Model View, View can be made relevant at the appropriate time updating of data. This design is also more general problems can be solved, the target separation, making a change to the target audience affect others, which targets those who do not know the details of the object being affected. This is described as Observer in the design model. Model type : Observer model is the object-oriented model, it is behaviour-based model. Model purposes : definition of hierarchical dependence relations between objects, or when a target value of the state change, all its dependent relationship with the object are notified and automatically updated. There are a variety of data may show a way, in different ways and may also show. When a way through a changed data, then the other should be able to show immediately that the data change and do accordingly.
Effect :
1. Abstract coupling. I only know that it has a target audience of some observers, the observers met each abstract Observer category simple interface, does not know their specific affiliation categories. This makes the coupling between goals and observers smallest and abstract.
2. Support radio communications. Needless to notify designated observers goals, how to deal with the observer informed decisions.
3. Possible accidents updated. We update logic, avoiding mistakes updated.
2.2 Faculty model
MVC is an important feature of View can nest. Nest can be used for any type of combination of local maps available, but also management of type nest. This thinking reflects the type and mix of components will be equal treatment design. This object-oriented design ideas in the area of Cambridge has been described as a design model. Model types : Cambridge model is the object-oriented model, it is also the structure type model. Model purpose : to target portfolio into tree structures to express "part-whole" level structure. Prepared for the use and combination of individual target audiences with the use of consistency.
Effect :
1. Definition of a target portfolio includes simple objects and the structure of the category level. Simple objects may be complex combinations of objects, and can be targeted portfolio mix. This customer-code used in the target areas can use simple combinations target.
2. Simplify customer-code. Needless to know their customers - a mix of target audiences is a simple target or can use these items in a consistent manner.
3. Easier to add new types of components. New components can easily be changed to a combination of customer-targeted codes.
2.3 Strategy model
Another important characteristic is the MVC can not change the View of changes View response to user input. This often requires a change in response to the logic of the system is very important. MVC to respond to the logic involved in the Controller. Controller of a category level structure could easily change to the original Controller appropriate, a new Controller. View Controller son used to achieve a specific example of such a response strategy. To achieve different response strategy, as long as examples of the use of different types of replacement will Controller. Also in the running time by changing the View Controller for users to change View of response strategies. This View-Controller relationship was described as an example of Strategy design pattern. Model types : Strategy model is the object-oriented model, it is behaviour-based model. Model purposes : definition of a series of algorithms, and their packaging, and ensure that they can replace each other, making algorithms can independently use its customer-change.
Effect :
1. Strategy category levels for Context definition of the relevant algorithms can be trusted or behaviour.
2. Alternative methods of succession. If the direct successor Context, with different acts will be added Context act, the realization of which would algorithm mixed up with Context, Context hard to preserve and expand, but can not dynamically changing algorithms. Will be enclosed in a separate Strategy category algorithms to enable algorithm independent Context change easily cut over expansion.
3. Can provide the same acts different date.
4. Strategy-must understand what customers between different.
5. Context and Strategy communications between costs.
6. An increase in the number of targets.
3. MVC in Web application system
Now some of the distributed systems such as Web-based B2B e-commerce system, suitable for use MVC framework. Through analysis from the perspective of high-level applications can be a target divided into three categories. Category is shown for the target audience consists of a group of commercial rules and data, there is a category that is receiving requests to control commercial target to complete the request. These applications often need to change is shown, such as web style, color, but also need to demonstrate the contents of the display. And the business rules and data to be relatively stable. Therefore, said that the frequent need to change the View objects that the business rules and data model to be relatively stable target, and that the control of the Controller is the most stable. When the system is usually issued after the View objects by artists, designers or HTML/JSP system managers to manage. Controller target applications development personnel from the development and implementation of rules for commercial and business development personnel from the target data, database managers and experts in the field of common completed. Show in Web?? or customers - control logic can be Servlet or JSP, dynamically generated Html. Generally used Servlet better than using JSP. JSP will be better with the Html code of separate codes for page designers and developers of separation efficiency. Servlet and JSP can complete all complete functions, actually JSP eventually converted into a Servlet. And control of the target system exists in every level, the coordination of cross-layer moves. Contain business rules and data objects exist in the EJB layer (EJB-centred model) or Web?? (Web-centred model).
3.1 View in the Web application system
View of the system shows that it fully exist in Web??. General by JSP, Java Bean and Custom Tag. JSP can generate dynamic web content using Java Custom Tag easier Bean, but it can show the logic of packaging, and more conducive to modular trusted. Some well-designed in a number of JSP Custom Tag can even be used in different system duplication. Model for control of JSP and Java Bean objects. JSP through Java Bean objects to retrieve the data model, the Model and Controller object is responsible for updating the data on Java Bean. In general, can we devise all possible screen that users can see all the elements of the system. Based on these elements, to identify the public part of passive components and dynamics. Can consider the use of templates means to separate the content generated JSP public, also need to change their generation Html or JSP from a JSP templates to dynamically introduce these different parts (include methods). Another issue to consider is screen option, when dealing with End users request template automatically available to show that the concern that users must know what is the screen components. So can consider all screens on the definition of a centralized document, such as a document or text document java. Taking into account the possibility of changes in future document definition screens, the best use of text documents such as a XML document, so future changes to the recompilation. According to the URL and user input parameters to shine upon the results of a screen, of course, likely to be made on the basis of the outcome of the implementation of actions to choose different results screen. Therefore, the need for a request for matching resources with document (XML), if a URL request several different results, it must specify in the document need to control the flow (a controller object), as well as the corresponding screen different flows.
3.2 Model in the Web application system
Model objects represent business rules and business data exist in EJB layer and Web??. In J2EE norms, the system needs some data stored in the database, such as user account information (account model), the company's data (company model), some not recorded in the database. If a user browsing the current catalogue (catalog model), the contents of his shopping (shopping cart model). Which one of these models exist in the data according to their life cycle and scope to decide. In Web?? a HttpSession and ServletContext and Java Bean objects to store data in the EJB layer is a data storage and logic EJB to. Web?? the Java Bean objects stored in the model layer model of the EJB object data copy. Because there are many different EJB tier model targets, so Web?? through a ModelManager to control the EJB layer object model in ModelManger background model can be used for packaging methods. In the EJB layer and the rules have all the data into EJB model is inappropriate. If the database can visit the Dao object model into objects. Dao can be encapsulated and the specific details of the database in the world, if we can write a different table, a number of databases, or even multiple databases. If the orders can be a model for OrderDAO, it may have to deal with Order table, table and OrderItemLines OrderStatus table. Value can also consider the use of targets. Value can be a target of securing long-range targets, because every time the remote object attributes could be a long-range redeployment process will consume network resources. EJB objects in the distance can be used instead target. In the distance, one-time items to be targeted instead of the value of all attributes.
3.3 Controller in Web application system
Coordination with the Model View Controller object to the request of users into the system to identify incidents. In Web?? generally a MainServlet (or Main.jsp), and receiving all requests, it can use screen flow management devices (ScreenFlowManger) decided next screen. There is a general request processors RequestProcessor contains all requests are needed to be done to deal with logic, such as the request translated into system events (RequestToEvent). Acting processors usually also includes a request for ClientControlWebImpl, it is logical to deal with the EJB layer in Web?? Acting. In EJB layer, a layer for EJB tier Web ClientController provide the CD visit. Another StateMachine used to create and delete ejb handle Web?? sent to the incident. Controller Another important function is synchronous View and Model data. ModelManger contained in a ModelUpdateManger, it puts events into a Model System assembly that all the needs of synchronous Model, and then notify Listeners do synchronous operation.
4. Concluding remarks
In recent years, with the Internet technology development and the emergence of new business models, the Web is based on a large number of applications. On how to design these systems architecture, and gradually there has been some convergence of opinion, the most important point is that its structure should be rational in the open. Demand than ever faster development of technology and design concepts, systems for the future, the cost of upgrading the smallest, research software systems architecture still very useful and necessary.

Bravo. And your point is?

Why are system and application sound files appearing in itunes?

Suddenly, over 900 system and application sound files, each about a second or 2 long, have appeared in my iPhone 4S music player. They've also appeared in my iTunes on my desktop iMac. Not sure whether they appeared on the computer first or on the phone first. I can't figure out why they appeared there or how to get rid of them (without also removing them from the system and applications which, of course, I don't want to do).
I searched through the discussions here and found several other people complaining about the same thing, going back a couple of years, but no solutions offered. I hope someone can offer a clue.

Thanks for the suggestions and help. While the cause of this problem is still obscure, we've managed, with an Apple tech's help, to remove the system/application sound files from both the iPhone and iTunes. We used Time Machine to backtrack to the point at which the sound files first appeared in the iTunes folder, then moved back one more day and restored the iTunes Media folder (where all the music was stored) and 2 iTunes files: iTunes Library.itl and iTunes Music Library.xml (we could also have simply restored the entire iTunes folder with the same effect). Then we synced the iPhone.
As for the cause, that's still a puzzle. From Time Machine, we were able to determine that the files were added between midnight and 12:47 AM on a particular day, but that computer was not in use at that time (the user was asleep in bed, and the only other person in the house at the time was me -- and I don't touch that computer).

References: Appearance different in Development System and in Run Time System

I noticed a difference the references appearance in Development System and in Run Time System. It seems to have no effect in the executable version but, per curiosity, someone have an explanation?

When LabVIEW builds an executable, it removes the parts which are not needed from the VIs (like BDs, or FPs of VIs which will not be opened). I'm assuming this is an extension of that where the icon is not copied over. Another option is that the RTE is simply missing the code necessary to display this specific this.
In any case, I would say it's a bug, albeit a minor one.
I don't think this is a bug, the references refere to a given CTL file, which is not present in the RTE, I think LabVIEW disconnects the reference form the typedef and only saves the properties needed.

Where would someone turn if they think they may be interested in apple/mac software development for systems and applications?

Where would someone turn if they think they may be interested in apple/mac software development for systems and applications? I do have some experience with industrial machine control programming. Not that it directly applies, however I have been involved in some types of programming.

You might start by reading this: http://www.guardian.co.uk/technology/gamesblog/2009/feb/10/gameculture-apple
I would check out the refurbished section of the online Apple Store before buying a used one from Craislist. They go quickly so you have to check often. It will be more than sufficent for you to work with.
There are more than a few such books, go to a book store near you and browse them yourself to see which one works for you.
For items 3 and 4 wait until you are ready for a commercial app and then seek help from a lawyer and an accountant.

Installed OS X Maverick on Macs...having problems slower system and apps freezing

I installed and downloaded OS X Maverick last week and installed it in relatively new Macbook Pro and IMac...both purchased last year...have experienced applications freezing, slower start up time several times, once was unable to start my Macbook Pro...had to reboot..and slower system response...anyone else experiencing the same?

Checked to see how much space is available ??
Click your Apple menu  top left in your screen. From the drop down menu click About This Mac > More Info > Storage. Make sure there's at least 15% free disk space.
As for slow startup, delete all apps in System Preferences > Users & Groups > Login Items
Same for HD > Library > StartupItems
Anti virus software can slow your Macs down if installed.

VISA Write differs between TS Development System and LV Run-Time Engine

Hi all
I made an application on LabVIEW to test BERs (Bit Error Rates), and I used VISA Write between two COM ports to exchange data.
Everything works fine using just LabVIEW.
Afterwards, I used TestStand to call my application (VI). The LabVIEW adapters from TestStand were set to Development System by default, and everything works OK!!
Finally, I needed to disable the development system, and set the LabVIEW adapters from TestStand to LabVIEW Run-Time Engine and I notice that the speed of the data exchange between the two COM ports decreased dramatically.
The only difference was the speed...because all the data (changed slowly in this case) arrived correctly on the other COM port too.
The symptom was the same as decreasing the baud rate...but the baud rate and all the other configurations remained the same. The only difference was the change between Develpment System to Run-Time Engine to notice this decreased speed between the exchanged data using VISA Write.
Any solutions for this?
Thanks in advance
Joao

Joao,
you state that using the LV Developement System as execution platform for your LV code modules result in faster datatransfer between the COM ports than using the LV Run-Time Engine.
So i am pondering: Does this refer to TS at all?
Please check the following:
Run you communication using a sole LV application in LV Developement System. This should be fast. Now build an executable of this application and run that one. Do you see the same behavior?
If there is no difference in a sole LV approach, there have to be some settings in the TS approach making this slow. So please let us know:
Are there different modules involved in that data transfer (which in fact points to the reply Christophe made)?
What about loading/unloading options of the modules?
How big is the hierarchy of the modules, e.g. is it necessary for the RTE to load stuff the Dev Env has already in memory due to loading a lvproj.......?
Could you provide a simple example sequence+modules showing this behavior?
What versions of LV and TS are you using?
hope this helps,
Norbert

HT201263 Hi Concern,i have updated my iphone 4 to ios7, now it becomes too much slow.all the applications take time to open, its touch response also became slow. How to update it again to ios6 please help

I have updated my iphone 4 to ios7 few days back, After that it becomes too much slow.all the applications take some time to open,
its touch response also became slow. .
One of my friends has also updated his iphone 4 to ios7,it is also facing the same problem.But the friend having iphone 4s is not facing any
problem with this new version.What i think iphone 4 has not too much good processor like iphone 4s & 5 to get it updated to ios7.
It destroys all the entertainment of using iphone.
How to update it again to ios6.
iphone 4 users please dont update iphone 4 to ios7.please

Sorry, but Apple does not provide a downgrade path for iOS.
Because downgrading is unsupported by Apple we cannot discuss it on these forums, but you can use Google to find information on how to install an older version of iOS on any device.
Note that you will void the warranty and loose official support by Apple.
Feel free to let Apple know at http://www.apple.com/feedback
Anyway, give a try resetting all your settings:
Settings > General > Reset > Reset All Settings

Cleaning old systems and applications from Mac

I want to clean up my computer of old system folders and applications that are not it use but am afraid some settings will be lost. Is there a careful way to do this? Is spring cleaning or another 3rd party software the best option. I particularly want to get rid of CS, CS2, and CS3 but I notice that each time I upgrade it pulls information from the previous install and I don't want to mess up my CS4, or CS5 settings.

"I particularly want to get rid of CS, CS2, and CS3 but I notice that each time I upgrade it pulls information from the previous install and I don't want to mess up my CS4, or CS5 settings."
Trash only the application. Leave the setting files alone.
"I want to clean up my computer of old system folders and applications that are not it use but am afraid some settings will be lost. *Is there a careful way to do this?"*
Leave the system folders alone is the +"golden rule"+ around here. Unless _you really know what you are doing,_ it's best to leave them be.
For cleaning up your computer of unwanted and/or unneeded files here are a few suggestions:
http://docs.info.apple.com/article.html?artnum=305454 Mac OS X 10.4: FileVault - "There isn't enough space on your hard disk..." alert
Empty the trash!
Open up your application folder & go through all your apps. Trash all the apps you no longer want and/or use.
An easier way to do this is to open the Application folder in list view & press the Command+j keys.
In the the dialog that appears, click the "This Window Only" button & the "Calculate All Sizes" check box.
Wait a bit until your file & folder sizes have all been calculated, then click the "Size" column to sort your apps from the fattest to the most anorexic.
Get rid of all your photo files you don't want and/or need. Same goes for those pics off the websites you downloaded (gifs, jpegs, etc.).
Get rid of all your music files you no longer listen too. Especially, if you already have the actual CD/DVDs or you can later redownload from a website.
Use Spotlight to make sure you got rid of everything. You can even trash directly from Spotlight!
Drag what you don't want and/or need to the trash. Better yet, download this neat little shareware app demo called AppZapper. It basically does all the work for you by not only trashing the apps but the apps preference files, caches & all its associated files.
Another software that does the above is AppDelete. Best of all this software is free!
Burn what you want and/or need onto CDs or DVDs.
Not everyone has the luxury of purchasing an external HD and/or Mobile accounts to store their "stuff.”
You can check with your ISP to see if they offer free storage space. Most if not all do now-a-days.
There are thousands if not millions of free storage facilities on the web also. Use your favorite search engine to search them out as they come in different storage sizes to fit your needs & wants.
Check for duplicate fonts.
Applications>Font Book
Select “All Fonts”
If you see any “black dots” next to any fonts this mean you have duplicates and/or multiple versions of these fonts.
To clean this up, select a “black dotted” font or the Apple + click to select multiple dotted fonts;
Edit>Resolve>Duplicates.
What the above does is turns off the duplicates & multiple version fonts. Not delete them.
More than likely the “extras” were installed by other programs and/or other users.
Clear out font caches
Use FontNuke. It does all the work for you. And, best of all it’s FREE.
Printer Drivers
Get rid of all the printer drivers you don’t need & use except the ones for your current printer(s)/scanner(s).
HD>Library>Printers Folder
If you accidently threw something out that you needed for your printer/scanner it can be easily obtained from the manufacturer’s website and/or from the CD that came w/the printer/scanner.
Garage Band
Has about 1GB of loops stored. Get rid of some some them. You surely don’t use, like and/or need them all.
HD>Library>Audio/Apple Loops>Apple>Apple Loops For GarageBand
Or just get rid of the Garage Band app altogether if you don’t use it.
Get rid of extra languages
Strip your computer down to your “native” tongue.
You can do this with a FREE utility called Monolingual. Another app that apparently does all the work for you. I’ve never used it. However, a lot of users here swear by & recommend it highly.
However, there is a warning for *native English speakers*. Make sure you keep BOTH English and English (United States).

Slow system and too many details after upgrading to OS/Lion

This MacBook Pro is my right hand, I was doing so great with Snow Leopard, Now everything takes twice longer. I cleaned up, reseted, reinstalled softwares, etc. same.
Too many details that doesn't work correctly.
-Safari constantly needs to be loading. Some times Firefox.
The track pad cant keep open a display box with a long list, once you try to scroll down.
-Preview, i used this app a lot, safe me time, DUPLICATE? instead of SAVE, i don't see the purpose. After editing images and safe them, gamma, color patterns and light appear distortion.
-iTunes volume doesn't comeback after using Skype or another app, remains low.
-Airport takes a bit longer to find a local network.
-There is not an extra space for the left and right scroll bottom on the finder window, sometimes this one disappear but mostly remains which makes it pretty tricky to open the last file at the bottom of the list. because the scroller is on front.
-External Drives, takes longer to connect or disconnect them.
Suggestions before i reinstall Snow Leopard.

guizz,
it sounds like you have come across the mother of all problems but i would like to help as much as i can.
first of all, i noticed that it took a few days after installing lion before my system was back to the full stride it had while running snow leopard give it some time and a few updates and lion should speed up because components such as ram take time to adjust.
the duplicate thing in preview is a new thing that came out with versions, one of the many new features in lion. i think it takes the place of the SAVE AS... command and you should still be able to save using the old command-s keystroke however part of lion includes an autosave feature so you really never have to worry about saving your work.
i personally cannot speak for safari or firefox even though i have both because i use google chrome as my web browser you can always give that a try.
in the system preferences under the general settings option you can change how the scroll bar is displayed on the screen.
i would suggest searching for other people who have had similar problems with itunes to try and find an answer
as for everything else your system may just need time to adjust to lion
good luck hope this helped a little

Slow system and plist

My system started slowing down and having gone through the forum,I deleted the plist list files. On deleting the files, I discovered that my settings have changed and has deleted my emails! Can I restore the settings and my emails?

HI,
Deleting the Safari .plist file has not effect on your e-mail.
Can I restore the settings and my emails?
You can restore from a backup using TimeMachine.
