20" iMac - How can I increase performance?
I have a 20" intel core duo with 2GB RAM. I mainly use Aperture & CS2 (in general not at the same time). I am overal 'satisfied' with the performance but after reviewing the running processes, feel that potentially there is some items I could disable to free up available memory and cpu. Any reccomendations? Also, any tweaks to the OS would be appreciated, I am a PC guy!! Thanks!
You have to look at where your bottlenecks are.
1) Rosetta. Running CS2 in Rosetta will be the largest bottleneck on speed. There's really nothing more that can be done here, since you have maxed out the RAM, which is VERY helpful for Rosetta speed.
2) Hard Drive. The hard drive is the slowest component of a modern computer system (orders of magnitude slower than RAM). But your iMac has a 7200 RPM drive, and you have maxed the RAM so there is minimal paging to disk, so no help here.
As far as disabling OS components, you can avoid the use of a background image in the finder. Use a simple pattern, or even better, create a 1x1 pixel picture in Photoshop and use that as your desktop picture. This will save RAM.
Disable Dashboard widgets that you're not using. Don't use anti-aliasing on Finder labels. Use thousands of colours instead of millions.
But in truth, all of this won't make as big a difference as avoiding the use of Rosetta. Your iMac is VERY powerful, and you've done the right thing by maxing the RAM. When 2GB sticks become a bit cheaper, I would go up to 4GB (the 2GB limit is artifical, due only to the lack of availability of larger chips).
Rosetta eats RAM, and slows the system down. I use MS Word every day on my Ph.D. thesis, and for this use, Rosetta is fine. But I also use Illustrator 10, and it can be a bit slow at times.
Frankly, until Adobe updates their apps, you've done all you can do. Remember, for basic graphic manipulation, try a program called Graphic Converter (http://www.lemkesoft.de/en/graphcon.htm), which IS a Universal Binary, and is VERY fast on my Intel iMac.
Hope this helps!

Mail has 16k messages, and performance is very slow, with loading times taking up to 5 seconds every time I open Mail.
How can I increase performance?
I'm running a MacBook Air 4GB 1.7GHz 10.7.2.
GrahamOne possible solution would be to organise your inbox into folders.
Its never relly good on any system to have one folder that has everything in it.
Try going to you web gui for that mail account and organise your folders and move mails from your inbox into corresponding folders for better organisation.
Several folders containing the same amount of one folder will usually load a little quicker as the folder may not be accessed to download its content unless veiwed.
So having 10 folders with organised content, and you inbox as an area thats to hold only new emails would work much much quicker with imap.
Most imap servers will only update the contents of a folder when its veiwed. -

How can you increase performance ?
Hello,
I am building a site but it's framerate is very slow.
I read some articles that Sprites are much faster then movieclips.
For example i have 5 long movieclips (4300 pixels in width). These clips scroll in horizontal direction to get a parallax effect.
One of these movieclips contains other movieclips. (all movieclips are not animating and are just graphics).
So I thought to increase performance to convert all movieclips to Sprites as I read that Sprites are better for performance.
I came up with this method:
function castMovieClipToSprite(source:MovieClip, recursive:Boolean = true):void {
for (var i:int = 0; i < source.numChildren; i++) {
var child:DisplayObject = source.getChildAt(i) as DisplayObject;
if (child is MovieClip && recursive) {
castMovieClipToSprite(MovieClip(child), recursive);
child = Sprite(child);
But the performance has slightly improved, but if i run the debugger I see that the child objects are still of type MovieClip.
Does anyone know other way to increase performance?
Thanks,
Chris.I also run some more test and noticed some strange behaviours,
Testlinks:
- Without the gradient ( http://www.rhbmprogress.nl/temp/cs/performanceTest1/ )
- With the gradient ( http://www.rhbmprogress.nl/temp/cs/performanceTest2/ );
Ps. I did not see any difference if I disabled the SWFProfiler so I left it on for test purpuse.
Desktop test,
Firefox version: 4.0.1.
Flash version: 10.2.152.32 (debugger version)
Test1 - > 60 fps
Test2 -> 55 fps
Internet Explorer version: 9.0811.1642
Flash version: 10.3.181.23 (debugger version)
Test1 - >60 fps
Test2 ->55 fps
Other destop computer test:
Firefox version 3.6.13
Flash version: 10.1.52.14 (no debugger)
Test 1-> 58 fps
Test 2-> 35 fps
Internet Explorer version 9.0.8112.1642
Flash version: 10.3.181.23 (no debugger)
Test1-> 60 fps
Test2-> 37 fps
As you can see there are some major difference between flash versions and browser types and versions.
So the solid fill seems to have a stable fps, but the alpha gradient fill does not appear so.
I wonder what flash version you used and what browser type and version -
How Can I increase performance of Query with Distinct Keyword
Dear Experts,
In my Query when I execute this without Distinct it give result very soon,
But when I excute this with Distinct its performance is very slow is there any option for increase the performance with Distinct .
I have to use Distinct according to our rewuirement.neither DISTINCT nor GROUP BY do sort. If you need to sort, use ORDER BY. Slight correction, they do a sort, but your results are not guarenteed to be sorted.
The overhead of a sort is incurred, if your results is large enough (my test below isn't) you will be sorting to disk. Which as we all know can be very slow.

How can i increase performance JSP with database?
Hi,
I am working a forum.
I have been facing a problem.
i am getting collection of records from sql server database to jsp page. here all the records to take long time (*delayness jsp with database*).
plz any bodies know that increase the permance, tell me.
thanks & regards,
k.s.kumaragain very bad idea never use Put DB Code or Business Logic or Special Service requests inside the servlets/backing beans.
Ideally the below is the method which is recommended for a Peformant J2EE application which focuses at modulality,configurablity,scalablity & performance.
http://java.sun.com/blueprints/corej2eepatterns/Patterns/index.html
Anyways,it might be a costly in terms of investment.Ideally i personally fell the below way/patterm could be comparable.
<!-- View / Presentation Layer -->
STEP 1 --> VIEW RENDERED(JSP renders view using a View Object/Objects)
STEP 2 --> USER (Fills Forms accordingly and request for an action)
<!-- Controller part -->
STEP 3 --> Controller(Servlet+Backing Bean)
STEP 3.1 ---> Mapps the request made into a View Object & Scopes it (Done by servlet )
STEP 3.2 ---> validation of the data in the VO (and servlet is responsible to find appropriate Backing Bean to pass on the respective View Object)
STEP 3.3 ----> Backing Bean takes help of a ServiceLocator Object(Singleton Object) and gets appropriate Business Object which takes care of all the appropriate business rule(Managed by Specific Containers)
<!-- Service Locator takes help of specific Stubs to provide access to specific business Object -->
<!-- MODEL PART -->
STEP 3.4 ---->Backing bean passes on respective View Object to the Business Object and Business Object apply business rule on the data recievd from the Backing bean and sends appropriate DTO to DAO Object(Singleton Object)
STEP 3.5 ----> DAO executes responsible DB query and returns a DTO/Collection of DTO to Business Object.
STEP 3.6 ----> Business Object apply business rules on the data and then passes it back to backing bean.
STEP 3.7 -----> Backing Bean receievs appropriate DTO/Collection of DTO sent by Business Object Update the View Object Accordingly.
STEP 3.8 -----> Depending on the results return by Business Object the backing bean returns to reference appropriate JSP to forward/redirect.
STEP 3.9 -----> Servlet identifies the reference returned and forward/redirects accordingly.
STEP 4 ---> Repeat STEP 1
NOTE: One can make use of any builtin frameworks(like struts,JSF,tapestry,Spring MVC,etc or your custom built framework in VC layers, EJB or Spring IoC or Custom Built Component Layer handling business objects and any ORM like hibernate,Oracle Toplink,Ibatis,JDO,JPA or specific custom devoloped DAO layer) to do this job.
Might Sound bit complicated but is a better way to plug & play with each layer and can enusure other layer is not distrubed because of change in one layer,distributes the load on respective layer & so on.
Hope that sounds logical

How do I get to “CSS Properties”? Do I click on Window > CSS Styles?
When I click on Window > CSS Styles, I do not see the text “Custom Class.”
I tried inserting (manually) the HTML code you suggested for the paragraph I want to change and nothing happened. I tried [<span class=”16px”>text came in here</span)]
I read in a tutorial that after you create a CSS style sheet, all you have to do is select the text you want to apply it to and then attach the style sheet to that text. I can imagine, however, that there are some special steps that one has to perform in order to do this.

You need to transfer your domain.sites file from your MacBook to your iMac. This is the file where iWeb stores all info and can be found under User/Library/Application Support/iWeb/domain.sites.
Transfer this file from your MacBook to the same place on your iMac and double click the domain.sites file and iWeb will open it on your iMac and you can update your site from there too.
