Bootcamp slowing down performance

Hi all,
I installed Windows 7 ultimate using bootcamp the other night, and I've been finding that on the mac side of things, things have gotten a bit slow. Loading applications, including native ones such as system preferences take up to 10-20 seconds for it to open up. I've reset the SMC, PRAM, fixed disk permissions while seeing not a huge amount of improvement.
Does anyone have any experience with this? I'm running 10.6.8 and my MBP is a early 2011 model.

Windows and OSx are in separate partitions and therefore do not affect each other when running. That said, there have been other posts in the Boot Camp forum from people who say they experience the same symptoms as you.
My suspicion is that you are running short on hard drive space since creating the Boot Camp partition. How much free space do you have in your OSx partition?

Does loading too many classes into jvm slow down performance?

hi all,
does loading too many classes into jvm will slow down performance. Our application is CPU bound, if we use any framework we need to load all the classes related to that framework in JVM. Does this have any effect on the performance of the JVM.
thanks and regards,
akmal

does loading many classes into jvm slow down performance.It will increase the time it takes for the JVM to load your application.
Our application is CPU boundThe time it takes the JVM to load your application is not likely to be an issue for you then.

Functions slowing down performance question

Hey there.
I've got a query that really slogs. This query calls quite a few functions and there's no question that some of the work that needs to be done, simply takes time.
However, someone has adamantly told me that using functions slow down the query compared to the same code in the base SQL.
I find this hard to believe that the exact same code - whether well written or not - would be much faster in the base view than having a view call the functions.
Is this correct that functions kill performance?
Thanks for any advice.
Russ

There is the performance impact of context switching between SQL and PL/SQL engines. Pure SQL is always faster.
SQL> create or replace function f (n number) return number as
2 begin
3 return n + 1;
4 end;
5 /
Function created.
SQL> set timing on
SQL> select sum(f(level)) from dual
2 connect by level <= 1000000;
SUM(F(LEVEL))
5.0000E+11
Elapsed: 00:00:07.06
SQL> select sum(level + 1) from dual
2 connect by level <= 1000000;
SUM(LEVEL+1)
5.0000E+11
Elapsed: 00:00:01.09

Do apps running in the background drain battery, slow down performance, or use cellular data?

I have heard that if you don't kill the apps running in the background, they will drain your battery, slow your other apps down, and could be using your data without any warning. I've looked all over the place for a definitive answer to this, but different people and websites provide conflicting responses and I haven't found any useful information regarding this issue directly from Apple. If anyone knows whether or not having apps constantly running in the background is harmful in anyway (and has a credible resource to back up their claim) let me know and provide a link to the answer if possible.

What do you mean 'running in the background'? Something that is 'running' will definitely use battery, nothing runs on air or whatever. If an app uses data while it's 'running' then it will use data. Why do you need a link, it's common sense isn't it? Slow the phone down? That I can't say definitively, but it stands to reason that it will.

Leopard slowed down performance on my G5

Not sure how to fix this, need some basic advice. I just loaded Leopard into my Power PC G5 and it's moving through applications, etc like molasses in January. Do I need to upgrade anything?

Hi! A couple of things may be slowing it down. One is spotlight which may be indexing drives and also Time Machine which takes a few hours for the initial backup. There could also be some temp files created that haven't cleared themselves. I usually recommend letting it run for at least 24 hours without sleeping to give it time to catch its breath. You could also have some apps that aren't Leopard compliant but those should have been checked for compatibility before loading Leopard. Usually though incompatible apps produce worse results than just a general slowdown. Tom

Many Queries slowing down performance?

Hi,
Our query response time is very bad, sometimes 30min to execute a query!
I noticed that there have been created a few hundred queries on the respective MultiCube.
Is the bad performance linked to the number of queries?
What advise can you give to speed up performance?
Many thanks!!

Infopath dataconnection slow down performance

Currently I am working on one project, and I created InfoPath form , that form has 20 to 30 fields.
Out of that 15 are dropdowns, and for those 15 dropdowns I have created secondary connections(11)
Due to so much of these connection My form taking much time to load,and same time there will be much more users will load forms, so it is creating much performance issue.
is there any way that my connections will be cached for all users or something like that .? or how to improve performance in this case ?
Please mark answer , if you think answer is helpful or correct.

Data queries are ALWAYS performed live... depending on the query, they may be performed during form load, or on demand (which may help if you are able to provide filters during lookup)... but no, there is no result caching.

Does re-installing system slow down the HD?

Hi
My MBP came back from repair with a new HD and OS 10.5 already installed. For various reasons I might want to wipe it and re-install the system software. But does this process of re-installing the system leave any 'debris' on the drive which might slow down performance in the long run? If so I may leave it, but it's a question I've always wondered about - when you re-install does the drive go back to being 'like new' again or is there a gradual accumulation of code which just adds more clutter?
Thanks for any help

If the OS or an app or whatever needs 10GB (for example) of free space, what does it matter if it's 10GB out of 100GB or 10GB out of 1TB?
I don't think it matters.
I thought that's what MacRS4 is saying
I did not understand it to be. The assertion was:
The 85% corruption thing fassumes a relationship of the largest file types to the size of the physical drive.
It does not. It assumes that the directory expansion varies with the total amount of data that needs to be stored. The 85% refers to the smallest amount of contiguous disk capacity needed to permit the file system to lay down new pieces of the Extents Overflow file. That does not have to do with the size of any individual file but with the total amount of data that needs to be accommodated in the file system/directory.
this question seems to asd for just the opposite, a rationale as to why a percentage would be needed, not a set amount of space.
My intention was to suggest there was a relationship (read percentage) between the total amount of data on the drive and the size of the filesystem. On a 100 GB HDD the filesystem will be smaller as the amount of data stored occupies a smaller amount of disk capacity. On a 1 Terabyte HDD 85% of total used capacity requires a corresponding size of directory. As I understand it the size of the directory varies in direct relationship with the amount of data stored on the drive and not to the total capacity of the HDD. The Micromat study (sorry, I have lost the link for that reference) found that the optimal capacity was 85% to avoid directory corruption.
As I noted in earlier posts, the equation may have changed with the advent of larger capacity drives, but I am not aware of documentation to that effect. I should also add that I am not by any means an expert. However, I am not willing to test to see how crowded my HDD has to be before I encounter an unrecoverable directory.
My asking for support for statements made is not by way of debate. I earnestly seek to learn more about this and other subjects from those who have information I do not, myself, have.

I'm about to buy a 27" i-Mac. I would like to connect my 30" Cinema Display to it as a second monitor. What will I need to do that? Will this slow down the overal performance?

I'm about to buy a 27" i-Mac. I would like to connect my 30" Cinema Display to it as a second monitor. What will I need to do that? Will this slow down the overall performance?

The new iMacs do not come with a MiniDisplayPort, they have Thunderbolt, so unless you are talking about purchasing one of the previous generation iMacs such as this refurbished model in the online Apple store, it won't work. And yes, if you are going to get the full range of video resolutions you will need the Dual-Link version.
For details see the store's web page on the Dual-Link display adapter.

Performance slows down when moving from stage to test schema within same instance with same database table and objects

We have created a stage schema and tested application which is working fine when we are moving it to another schema for further testing ( This schema is created using same scripts which were used to create objects in staging schema) the performanc of application (Developed in .NET) slows down drastically
Some of the store procedures we have checked at Databse/SQLdeveloper level are giving almost same performance but at Application level there is lot of difference
Can you please help

Browser based InfoPath Forms in SharePoint 2010 performance has slowed down after SharePoint 2010 SP2

hi All,
Our Browser based Infopath forms have slowed down drastically after applying SharePoint 2010 SP2. Prior to this, we had SharePoint 2010 SP1 and the timings was around 10 seconds (single user) for the entire infopath form to be displayed which has 10-12
views and 5 data connections and 15 business rules and around 100 fields.
But now after applying sharepoint 2010 sp2, the performance has slowed down and it now takes for a single user around 50 seconds.
Refer to the link below, which we followed by applying the patch as well, but the performance is still the same very slow.
http://social.technet.microsoft.com/Forums/sharepoint/en-US/0b673324-01c4-49f7-86cb-647aa43fefd6/infopath-browser-forms-extremely-slow-after-service-pack-2-upgrade?forum=sharepointadminprevious
We have raised a ticket with Microsoft, but there is no concrete resolution as to what component of the infopath has made the form rendering and display slow.
Can someone point me to the right resource or knowledge base where i can do a kind of debug, which tells me exactly which infopath dlls are the issue or which part of my form is taking more time. I am using AOLPageTest and Fiddler, but they do not give me
any details where exactly is the bottleneck.
Any tools that give me the details of the bottleneck.
Thanks and appreciate your help in this.
Regards
Ram
Thanks Ram

hi inderjeet,
The application has gone live and its on production, the same application is on pre-prod and UAT, system testing and integration environments.
The infopath form used to work very well on all these environments before we installed sharepoint 2010 sp2. but the moment we installed sharepoint 2010 sp2, the infopath forms have slowed down.
Microsoft has acknowledged that there is an issued with sharepoint 2010 sp2 and infopath form performance, but they are not able to provide an appropriate fix on this.
We have another environment where there is no sharepoint 2010 sp2 applied only sp1 is applied and the infopath form works very well within fraction of seconds.
So your point no. 1 and 2 and 3. does not reveal anything. Fiddler does not give any detailed component by component breakup where the time is taking more.
The form used to work very well before we applied sp2.
I want to know a tool that gives me exactly component by component grant chart kind of breakup of time taken when the infopath url is requested on the browser.
Thanks

JVM performance slowed down after

Hello all,
My java application is heavily multithreaded and its supposed to run as a 24/7 service. Its supposed to collect SMS from different servers, store in memory/flat-files and send them to clients.
The application has been running for the past 6 days and
the JVM has slowed down considerably. (performance has gone down)
Initially the app used to receive/send arnd 50 SMS per second and now it process aroubd 20-25 SMS per second.
I've been using Your kit profiler to profile my app.
The maximum heap I allocated was 500MB; the alloted Heap shown in the
profiler is 95MB and the used Heap is 65MB
The CPU usage looks fairly stable,i.e. it does go up when SMS comes in
and i/o operations takes place and goes to 0% when no process is being done.
memory usage also looks fairly stable.
(No explicit memory leaks)
The application has over 133 threads and that stays the same as per
the profiler tool kit.
Also in my application I have a maintainance phase at 23:00 hours during which i do some cleaning work like
-deleting of expired SMS from memory
-deleting old log files
-deleteing other flat files
-and finally I explicitly call the garbage collector
What should I look in - to maintain the performance, should I not explicitly call
the GC and let JVM do it on its own? or is it beacause the heap space has become fragmented? - I do make a lots of read/writes from/to the objects stored in Heap.
I also make around 160,000+ read/write from/to flat files in the hard disk.
Could this cause the JVM to slow down?
Any suggestion on this will be great.

Initially the app used to receive/send arnd 50 SMS
per second and now it process aroubd 20-25 SMS per
second.
I've been using Your kit profiler to profile myapp.
Does it have CPU profiling? If yes, then you can look
at where the time's being spent when processing a
message.
It does have a CPU profiling graph, but there is nothing much i can infer from it, I can see the graph peaking to 60-80% CPU usage when SMS are comming in (i.e. SMS is received, stored in memory & a copy is also put in the flat file - which is a read/write I/O operation, so I would defenitely expect the CPU to peak up); this peaking up would normally happen between 6-9am when lots of SMS come it to my app. The rest of the time (in the afternoon & evening) CPU is 0% ; so I can defenitely rule ot memory leak right?
its difficult to find out the time taken to process every message; the rough estimate I got from the log file is 50SMS / Sec. i.e. 50SMS receievd via TCP/IP; then store it in flat file & memory and also deliver it across to a client via socket; get a response back; change some status in memory and also in the flat file; this count of 50 has defenitely dropped to 25-30 in 6 days.
>
The maximum heap I allocated was 500MB; thealloted
Heap shown in the profiler is 95MB and the usedHeap is 65MB
So not a memory problem.
The CPU usage looks fairly stable,i.e. it does goup
when SMS comes in and i/o operations takes place
and goes to 0% when no process is being done.So not a background thread that's run amok
(probably).
The application has over 133 threads and thatstays
the same as per the profiler tool kit.You could be running into contention for a shared
resource. This will show up in the CPU profiler, or
you can get a "quick and dirty" report by hitting
Ctrl-\ in the window where the JVM is running (or, if
on Unix, sending SIGQUIT to the JVM process). This
will send a thread dump to the console. Look for a
lot of threads "wait"ing on some object, then look
for the thread that holds that object.
You are talking of possible dead-locks right? thats something i@ve go to llok into; the profiler does lists ot a list of possible thread-deadlocks. but all of them are purposefully made into TIMED_WAITING ; would that cause the performance to drop?
>
What should I look in - to maintain theperformance,
should I not explicitly call the GC and let JVM doit on its own?
Never call GC directly. The JVM will do it when
necessary. Plus, you don't appear to have a memory
issue.
Yep, would change that and avoid calling GC directly.
>
I also make around 160,000+ read/write from/toflat
files in the hard disk. Could this cause the JVM toslow down?
Ahh ... flat files in a single directory? A lot of
files in one directory will definitely slow things
down, especially if you're opening them for every
read and write: the OS has to scan the entire
directory to find the file.Nothing much I can do there.
>
Does performance improve after your nightly cleanup?
If yes, and you're removing old files, then this is
an indication of the problem.I'll look into the logs to see if there is any increase in performance after GC and clome back

Why adobe flash player slows down all browser's performance?

I rememeber longer ago there were problems with flash player plugin inside Mozilla's Firefox browser causing the plugin to crash: Adobe Flash plugin has crashed - Prevent it from happening again | Firefox Help
After a recent update (17,0,0,134) it almost never crash but it slows down all browsers performance untill it finally launches next video. Almost the majority of all news sites use flash player
to launch its' commercial. And it has several such boxes with commercials, for example: www.lrytas.lt
And while I'm listening to music via youtube and on the other tab reading news on that site, when music clip ends and the browser starts to load other music videoclip,
then the whole browser's work is paralysed - I can't write text, cannot scroll down, cannot click any link. All this is because the system is busy while in youtube next clip is loading.
Mouse marker becomes into round rotating circle indicating loading procedure (firefox is not responding). And it takes time - up to 10-15 seconds to launch new video. Then sudenly all my actions is executed after such pause - my text is typed,
my scroll down and maybe link is pressed. All this slowing down procedure is annoying. It wastes a lot of time. I open task manager and I see that Firefox is taking 900.000 or 1300.000 K of memory. My OS is Windows 7.
I close whole firefox.exe process and then it automatically close plugins. Then I open the browser again and it ask to automatically recover interrupted sites, I agree with it and then it opens everything again. And again
it is working continuously for some time untill slows down browser again. With more tabs more problems. Moreover, view of a video sometimes comes too late too. Some images are lost as system is too late already because
loading procedure took too much resources.
Long long ago flash player was better. But today with a rise of new ****** substandart computers like iphones ipads you have to evolve the player in such a way that it has to play on everything, but its performance on different platforms
is not the same.
Who is guilty - my PC, Firefox or the plugin? Or maybe I am?
In My Cold Opinion, users actions can't be ignored. The preference should be user's continuous control over a system load.

You are right about high CPU usage. It was even when playing various computer games. I don't have problems anymore. But not because I disabled all addons. I did these things:
In the Location bar, type about:config and press Enter. The about:config "This might void your warranty!" warning page may appear. Click I'll be careful, I promise! to continue to the about:config page.
Search for dom.ipc.plugins.flash.disable-protected-mode in the list of preferences.
Double-click on the preference to toggle its value from false to true. (If the setting is already true it means that Flash Protected Mode is currently disabled.)
Close Firefox.
Restart Firefox.
And since then I don't have that particular problem with overloading. I just disabled some of flash protected mode. How is that related with "overloading"? Strage. Hardware acceleration I've enabled again as without it whole text field in news sites is sometimes black.
Thanks anyway Mr.
