Better memory usage

Hi,
why is iTunes not using my RAM to store the songs of the current playlist. I have more than 1GB, so the playlist would fit easy into the RAM. That way the harddisc could spin down when I am just listening to music (e.g. at night before going to sleep). This in turn would make the computer more quite and prolong the battery life.
Kurt

Is there a way to adjust the amount of prefetch memory? If I am not mistaken, my harddrive doesn't spin down even I have only iTunes running (plus the usual background tasks), but still, there should be enough free memory and I am not changing tracks (since I lie in bed).

BackgroundMediaPlayer high memory usage

Hi, I have a problem with WP8.1 Background task with BackgroundMediaPlayer. When I have just the simplest app, which have virtually zero logic in both the task and and app, when the task is started, it takes 15MB of memory. When playback starts, it jumps
to 21 MB, which leaves me about 4 MB (since the limit is 25 MB). This is just ridiculous. (I use MemoryManager.AppMemoryUsage to get used memory).
What I find even more stupid is the fact that when I run the app in emulator, the memory usage is 5 MB on start, after start of playback 11 MB. So I am left with 14 MB, which is ok.
I created a simple project, if you are interested, download it here: http://bezysoftware.net/files/App13.zip It will notify you about memory usage in background task using toasts.
Any ideas what to do? Beside rewriting everything in C++ - I already have an app ready in C#.

Hi bezysoftware,
Looks like emulator performs better than the real device? I'm not quite understand what do you mean by "playback" start, what's the difference between task start and playback start?
And sorry I cannot repro the issue on my emulator, always 7.7MB instead of 11MB as you mentioned.
I also tested with my Lumia 630, it only use 3MB when start and use 7MB when running, I cannot repro the issue.
I would also suggest you tell us what kind of device you are using, perhaps it related with the test device.

Extremely high memory usage after upgrading to Firefox 12

After I upgraded to Firefox 12, I began frequently experiencing Firefox memory usage ballooning extremely high (2-3GB after a few minutes of light browsing). Sometimes it will drop back down to a more reasonable level (a few hundred MB), sometimes it hangs (presumably while trying to garbage collect everything), and sometimes it crashes. Usually the crashing thread cannot be determined, but when it can be, it is in the garbage collection code ( [https://crash-stats.mozilla.com/report/list?signature=js%3A%3Agc%3A%3AMarkChildren%28JSTracer*%2C+js%3A%3Atypes%3A%3ATypeObject*%29] ).
I was able to capture an about:memory report when Firefox had gotten to about 1.5 GB and have attached an image.
A couple of things I've tried. I have lots of tabs open (though the Don't load tabs until selected option is enabled), so I copied my profile, kept all my extensions enabled, but closed all my tabs. I then left a page open to http://news.google.com/ and it ran fine for several days, whereas my original profile crashes multiple times a day.
I also tried disabling most of my extensions, leaving the following extensions that I refuse to browse without:
Adblock Plus
BetterPrivacy
NoScript
PasswordMaker
Perspectives
Priv3
However, the problem still happened in that case.
Don't know if any of this helps or not. I'm looking forward to trying Firefox 13 when it comes out.

hello, thanks for reporting back with detailed information.
from a brief look at your extensions i don't recognize any known (to me at least) memory leaking ones. in the last weeks there were also reports about the java plugin causing high memory consumption in combination with firefox 12 - in case you have it installed in firefox > addons > plugins try disabling it for a few days & test how firefox is behaving with many tabs.
& although probably not related to the memory problems you could update your graphics driver to get better results with hardware acceleration in firefox - this is the latest driver by intel for your model & os:

High disk usage/high memory usage.

i keep getting high memory usage and high disk usage in ps cs6.
its slow when i open a file. how can i solve this problem.
thank you.
philip.

Not to put too fine a point on it, but more than what? More RAM is almost always better, but you haven't answered most of the questions posed here. The answer might be different if you have 2 GB of RAM or 32 GB of RAM already. A 9 megapixel document could get rather large with a lot of layers, but again you've neglected to give any hard info about its size.
Regarding your video card, that's a bit of a judgment call you need to make. For Photoshop CS6 I currently advise people to try to get a video card that gets a score of 1000 or better on this benchmark: http://www.videocardbenchmark.net/high_end_gpus.html
Video card speed will matter when you're editing those 3D components and video card VRAM will also matter, but possibly even more importantly your GeForce 320 is a bit old, and nVidia may just not be doing their best driver work for it any more.
Everything in general will run more smoothly with a powerful modern video card. I like to recommend a VisionTek ATI Radeon HD 7750 - or if the computer power supply and your budget allow, the even more powerful 7850. VisionTek does a very good job with their hardware, IMO, and it comes with a lifetime guarantee.
Keep in mind that if you switch from nVidia to ATI or vice versa, you should carefully sweep your system to ensure all files from the old card are removed, then visit the web site of the new card's maker and download/install their latest display driver release.
Best of luck.

High Memory Usage

Updated to 4.0 today and have things about where I would like them, but memory usage is at least 4 times higher than 3.6.15. I attribute some of that to AFOM not being compatible and being disabled, but I can hit 1.9GB with all my open tabs where 3.6.15 is around 500MB.
Is there something I can do? A memory manager for 4.0?
I'm afraid this will turn out to be unusable.
~Bob

Well, FF4 definitely uses more memory than FF 3.6. No doubt for me. I have it under control by being lucky enough to get a beta copy of a memory manager for FF4, but without that I would have had to switch back to FF 3.6.
It still uses more memory than I think it should and strains the resources on my machine.

Internet Explorer - Memory Usage

Hi,
I have developed a VC model and deployed it in the portal. When i execute the model in internet explorer 7 or 6, the memory usage keeps building up and does not drop even after getting all the data. I have got couple of popup iviews in the model which when executed increases the memory usage further more and eventually internet explorer stops responding.
Currently the only way to clear the memory is to close the Internet explorer window. Is there any other way to flush out the memory after the data has been retrieved from the back-end.
Regards,
Ravi.

Hi Ravi,
I googled in and found few links which can be helpful to you.
http://cybernetnews.com/browser-comparison-internet-explorer-firefox-chrome-safari-opera/ - which is all abut the memory tests which were conducted for various browsers including ie regarding the usage of memory.
http://www.bigresource.com/PHP-Flush-clearing-buffer-3rXPLSop.html
http://www.wimpyplayer.com/docs/howto/clear_cache.html - which tells about the way to flush out the browser memory for better usage.

Memory usage gets high and stays high

I'll use my current project as an example, but I've been noticing this issue ever since I started monitoring my computer's memory usage. If I have an hour long Premiere CC timeline and render it, during rendering my computer's memory will go up to about 90%. After rendering is done, task manager shows that Premiere is still using about the same amount of memory, and it stays that way until I restart my computer. It's like it has locked into using certain resources and cannot let go. Any way to remedy this? I currently have 10gb memory (ordered 2gb more that is arriving this week), so it's not the fastest machine around, but should handle memory better in my opinion. I am fine with the rendering speed itself, it's just the tied up resources afterwards that seem like it could be fixed.
One more point - one solution is forcing Premiere and all its components to close. This gets the memory back to normal. Unfortunately, sometimes after I render a long timeline and force restart Premiere, when I get back all my render files don't properly reconnect and I'm forced to re-render the timeline. The fact that it doesn't reconnect to the render files is another related-issue I need help with too, if anyone can offer feedback. Thanks!

On the lost renders.

On the memory issue, I'm not sure anything is wrong here. You say PP releases it when you close PP. That's the expected behavior.

High Eden Java Memory Usage/Garbage Collection

Hi,
I am trying to make sure that my Coldfusion Server is optomised to the max and to find out what is normal limits.
Basically it looks like at times my servers can run slow but it is possible that this is caused by a very old bloated code base.
Jrun can sometimes have very high CPU usage so I purchased Fusion Reactor to see what is going on under the hood.
Here are my current Java settings (running v6u24):
java.args=-server -Xmx4096m -Xms4096m -XX:MaxPermSize=256m -XX:PermSize=256m -Dsun.rmi.dgc.client.gcInterval=600000 -Dsun.rmi.dgc.server.gcInterval=600000 -Dsun.io.useCanonCaches=false -XX:+UseParallelGC -Xbatch ........
With regards Memory, the only memory that seems to be running a lot of Garbage Collection is the Eden Memory Space. It climbs to nearly 1.2GB in total just under every minute at which time it looks like GC kicks in and the usage drops to about 100MB.
Survivor memory grows to about 80-100MB over the space of 10 minutes but drops to 0 after the scheduled full GC runs. Old Gen memory fluctuates between 225MB and 350MB with small steps (~50MB) up or down when full GC runs every 10 minutes.
I had the heap set to 2GB initally in total giving about 600MB to the Eden Space. When I looked at the graphs from Fusion Reactor I could see that there was (minor) Garbage Collection about 2-3 times a minute when the memory usage maxed out the entire 600MB which seemed a high frequency to my untrained eye. I then upped the memory to 4GB in total (~1.2GB auto given to Eden space) to see the difference and saw that GC happened 1-2 times per minute.
Is it normal in Coldfusion that the Eden memory would grow so quickly and have garbage collection run so often? i.e do these graphs look normal?
Also should I somehow redistribute the memory available to give the Eden memory more since it seems to be where all the action is?
Any other advice for performance improvements would be much appreciated.
Note: These graphs are not from a period where jrun had high CPU.
Here are the graphs:
PS Eden Space Graph
PS Survivor Space Graph
PS Old Gen Graph
PS Perm Gen Graph
Heap Memory Graph
Heap/Non Heap Memory Graph
CPU Graph
Request Average Execution Time Graph
Request Activity Graph
Code Cache Graph

Hi,
>Is it normal in Coldfusion that the Eden memory would grow so quickly and have garbage collection run so often?
Yes normal to garbage collect Eden often. That is a minor garbage collection.
>Also should I somehow redistribute the memory available to give the Eden memory more since it seems to be where all the action is?
Sometimes it is good to set Eden (Eden and its two Survivor Spaces combined make up New or Young Generation part of JVM heap) to a smaller size. I know your thinking - what make it less, but I want to make it bigger. Give less a try (sometimes less = more, bigger not = better) and monitor the situation. I like to use -Xmn switch, some sources say to use other method/s. Perhaps you could try java.args=-server -Xmx4096m -Xms4096m -Xmn172m etc. I better mention make a backup copy of jvm.config before applying changes. Having said that now you know how you can set the size to bigger if you want.
I think the JVM is perhaps making some poor decisions with sizing the heap. With Eden growing to 1Gb then being evacuated not many objects are surviving and therefore not being promoted to Old Generation. This ultimately means the object will need to be loaded again latter to Eden rather than being referenced in the Old generation part of the heap. Adds up to poor performance.
>Any other advice for performance improvements would be much appreciated.
You are using Parallel garbage collector. Perhaps you could enable that to run multi-threaded reducing the time duration of the garbage collections, jvm args ...-XX:+UseParallelGC -XX:ParallelGCThreads=N etc where N = CPU cores (eg quad core = 4).
HTH, Carl.

OS X Yosemite Safari memory usage

Safari's memory usage under Yosemite continues to increase until system stalls due to paging. The memory gets to about 60G before the stall. Also, the process SafariDAVclient exhibits the same behavior. This started after I reinstalled Yosemite. Reinstalled again, no better.
Anyone have a solution?

Mailclient memory usage

Hi!
I've been developing a supposedly lightweight email client for my own use, to learn java better. The problem is that when I run it, it is not exactly as lightweight as I'd like. It sucks up 20-30MB of memory, which I think is quite much, as at the moment it's not really more than a mail notifier.
Is this due to JVM overhead or because of poor programming on my part? If the latter, are there any guides or similar to avoiding the most common pitfalls of excessive memory usage in java?
//T
EDIT: the only GUI classes that I'm using (except for when adjusting setting and such) is a subclass of awt.TrayIcon
Edited by: ojve on May 10, 2008 9:50 AM

I doubt your code takes up 30 MB, so I would venture a guess that it is also showing the JVM.

What are Microsoft- or other's-best practice or recommendation of Disk usage, CPU usage, memory usage monitoring to prevent system trouble ?

We use win2003,win2008,win2012 servers.
I heard somewhere that Microsoft recommendation threshold of disk usage monitoring is ( free disk space >= 15- 20 %) , if I remember correctly, but how about CPU usage and memory usage monitoring ?

0.5 MB program has 832 MB memory usage even before it is run

I just uninstalled and re-installed LabVIEW 2011. I was hoping this would do something to lower the memory footprint. Alas, it did not make any difference. This is what I see:
- When I launch LabVIEW, it uses 94 MB even before I have opened a single VI, i.e. only the front end uses this much memory.
- When I open the VI (the size of the .vi file is 549 KB), memory usage goes up to 836.4 MB. This is before I have even run the program.
- Finally, when I run the program, memory usage jumps to 1.17 GB.
I find this memory usage grotesquely high. Can anyone please shed some light on what can be done? I have uploaded the VI. It's a rather simple VI.
Thanks,
Neil

1) If I understand correctly, what you are saying is that when I open the VI, the data structures associated with the intensity charts and waveform graphs are initialized to default values (e.g. 0), so there is memory usage even before the program is run and anything displayed, right?
Yes, a huge array still takes a lot of memory, even though it compresses well for storage inside the VI. Once the VI is ready to run, these arrays need to be allocated in memory.
nbf wrote:
2) Is there an alternative to using the value property node that doesn't duplicate the memory content? (e.g. something like pointer or reference in C++?)
One possiblity are data value references. You can open a DVR and fill it inside the subVI, then extract slices later as needed. If done properly, you can also keep the 2D data in a shift register (yes, please learn about them!).
nbf wrote:
4) Regarding the clearing of the indicators, could you please tell me how to do that, without removing the color ramp settings?
The color ramps can be set programmatically using property nodes based on array min&max and you can assign colors for the ramp values at will.
nbf wrote:
5) You are correct that I am displaying 4000x2000 array data in an intensity graph with 400x200 pixels. But then I change the min/max of the charts/graphs to zoom into the region of interest; I can identify the region of interest only after displaying the full 4000x2000 array of data. I don't know if there is a way around this.
Do you really need to show the 2D data in three different transforms? Maybe one intensity graph is sufficient. You can apply the other transforms on the extracted slices with <<1% of the computing effort. What is the range and resolution of your data? Do you really need DBL or is a smaller representation sufficient (SGL, I16, etc). From looking at the subVI, the raw data is U16. The subVI also involves a coercion to DBL, requireing another data copy in memory. When running, make absolutely sure that the subVI front panel is closed, else additional memory is used for the huge array indicator there. For better performance, you might want to flatten the subVI to the main diagram or at least inline it.
nbf wrote:
6) Yes, I use the continuous run mode instead of a toplevel while loop. Is there a disadvantage to doing that?
As Samuel Goldwyn ("A hospital is no place to be sick") might have said: "Run continuously is no way to run a VI"
Run continuously is a debugging tool and has no place in typical use. What it basically does is restart the VI automatically whenever it completes, and as fast as the CPU allows. It is mostly useful to quickly test subVIs that don't have a toplevel loop and play with inputs to verify results. Any toplevel VI needs a while loop surrounding the core code. Period!
So, my suggested plan of action would be:
Use a while loop around your toplevel code
Decide on the minimal representation needed to faithfully show the data.
Keep a single copy of the 2D array in a DVR
You optionally might want to undersample the data for display according to the pixel resolution and use other means of zooming and panning. For zooming, you could extract a differently sampled small array subset and adjust x0 and dx of the axes accordingly.
Use a single 2D graph (if you need to see the various transforms, add a ring selector and transform the 2D array in place. Never show more than one intensity graph.
See how far you get.

WinXP and Vista memory usage with Illustrator CS2 - is Vista winning?

Dear forum.
I have an AI-template file where I insert some very large PNG files into it, modifies the template a bit and then I print the the resulting document in PS-format. The PNG files may be as large as 100 MB (24-bits, approx. 100 mil. pixels in total). It appears that while a Vista-based machine has no problem loading one or even two copies of these huge files into memory, a WinXP-based machine can't even load a single file into memory. Instead, I a dialog box with the message: "Could not read the file because the plug-in could not understand this file". Is it really a faulty plug-in or is it just CS2's way of saying "not enough memory" in a quirky way?
All in all, I would like to hear whether someone has the same experience with Vista, ie. it seems to be better at memory management or better at allocating memory for Illustrator CS2, enabling it to load large PNG files.
The specifications of the WinXP-based machine:
Pentium 4 2.6 GHz
3 GB RAM
Virtual memory 4095 MB in a physically separate drive from the OS disk
All Visual Effects are turned off
Has Illustrator CS2, Adobe Acrobat 7 and Distiller installed (and a few auxilliary programs)
The specifications of the Vista-based machine:
Dell OptiPlex 740SF
AMD x2 5000 (2.6 GHHz)
2 GB RAM (667 MHz, 2 x 1 GB)
250 GB SATA disk
Windows Vista
Adobe Creative Suite 2 Standard + Adobe Creative Suite 3
Thanks!

Hi, everyone
I got a new t440p 20ANA00UHH (8GB RAM, win8 64bits) about one week ago. It works really well, but its memory usage confused me. In Task Manager, the "Performance" option shows memory is 68% (5.4G in use), but "Users" option shows memory usage 66% (1019.5M in use). Is that normal ? I just opened some websites and word files.

Ps CS6 Memory usage 14GB from 50 meg file???

Hey,
Does this memory usage make sense?
I'm working on a 48 meg file, but my RAM usage was up to 13.9 gigs. I just restarted Ps and opened the file and it's up to 10.7 gigs.
Previously I was always maxing out 10 gigs everyday out of 12 available gigs in the machine also working on small files.( 25-30 meg on average) IT tried playing with things forever and finally just tried ordering more RAM. They ended up putting 28 Gigs in the box. And I'm really not seeing any advantage in Photoshop, other than my system still runs OK outside of Ps while I'm working. (Well Rhino 3D still crashes from being out of memory, even though there was still 6 gigs free??? but that's for another forum) Mostly it just freaks me out how much RAM it's using for such a small file...?
I'm just drawing, no filters, not too many layer masks. I do have maybe 15-20 vector smart objects in the file, and I'm at 147 layers. The issue I was having is Pen lag on the Cintiq when I draw starts getting horrible as the RAM usage gets higher. I had been restarting Photoshop constantly to get it to release RAM. But I haven't the last couple days since they doubled the RAM in the machine. And obviously on restart the file still needed a lot of RAM???
Anyone got any sugestions? I can live with the lag, sucks, but I can still work. I just don't understand why these small files are using so much RAM. Back in the day on 32 bit systems with 4gigs of RAM I would sometimes create posters/covers/magazine spreads that were 1.5- even 4 gigs that would have to be saved as Tiff's because PS didn't support a file that big. This machine runs like that everyday. At home I've been doing some freelance book covers that get up to 450 megs now and then and it still runs better, Cintiq at home draws smoother than this machine that costs 3-4 times more!
It's a win 7 64 bit box, 2 Dual core 2.4 Xeons. two quadro 2000's, now 28GB ram, OS on a 560?GB drive with files on a Terrabyte drive that gets backed up. My hardrives arent rated very high, 5.9, but at least im working local to the machine as the network is slow as heck around here!
Thanks for any suggestions anyone might have!

Your issue is stroke lag drawing. You state nothing about the brush and tool being used. Looking at your hardware and knowing Photoshop is using a lot of ram its most likely swapping a lot ram to scratch disk space. Faster disk may help. Also having two quadro 2000 does not improve Photoshop performance over having just one. Yes Photoshop does not give back RAM it allocate during a session even if you close all the open documents. This may well not be a bad thing. Photoshop is surly managing the RAM space it allocates. Having a lot of ram to work with may well cut down on Photoshop RAM swapping and speed thing up.
Your lag problem may not be a ram problem. Some brushes require GPU support and the size of the rush can easily increase lag. For example if I boot my machine and look at RAM used window 7 64bit professional I see 3.5GB allocated 36.5GB free. If I start CS6 open a new document 11"X 14" 300dpi fill it with a spectrum gradient I see 5GB of ram. In use. If I select the mixer brush tool and a large brush size and make quick brush strokes there is quite a bit of lag and my video card is a quadro 4000 a little faster then your quadro 2000. My swap space is on SSD much faster then spinning disk ratting 7.9 out of 7.9.... and I have dual 6 core xeons.
Some brush type tools like blur, smudge, dodge, burn sharpen require a lot of sequential repetitive processing .. a large tip smudge always seems lag on forever... Its the repetitive nature of the processes that cause the latency not so much the compute power.

CPU/memory usage of AIR application under Mac 10.4.10

As my AIR application uses a lot of CPU/memory under Mac
(seems better in Windows), I decide to do some basic testing. I
create several applications with different level of complexities.
Below is a table of CPU/memory usage when the application is simply
sitting there. A brief description of the application can be found
in the end of each line.
Here are some results:
[1] Even for an empty application, CPU usage is not zero
(most non-AIR application has 0 CPU usage when doing nothing). Also
the memory usage is huge, comparable to Finder on my computer.
[2] Empty application has 7 threads running.
[3] Indetermined progress bar costs a lot of CPU; and I guess
any other animation costs a lot of CPU too. But if they are
invisible they are fine.
[4] running timer costs CPU.

As to my own application, it's much bigger than these simple
ones. The CPU usually stablizes to 20% and VSIZE is about 1G. There
is no timer running. When I leave the application open for a few
hours, the application will eventually freeze and I have to kill
it.
I am wondering if there are any articles or documents
explaining AIR's CPU/memory usage. And also if AIR is planning to
improve the performance in the next release.

James, thank you for the very fast answer! I did various tests on the weekend on my computer and computer of my friend.
And I can say, that Debug flag doesn't affect memory consumption. They still eat memory. My steps to reproduce are as follows:
(Windows 7 32 bit)
Photoshop CS5:
1) set HKEY_CURRENT_USER\Software\Adobe\CSXS2Preferences\PlayerDebugMode to 0
2*) check HKEY_LOCAL_MACHINE\SOFTWARE\Adobe\CSXS2Preferences (just in case)
3) Compile HelloPhotoshop example to ZXP and install via Extension manager
4) restart computer
5) Run Photoshop CS5 - Memory consumption: 100 096 KB
6) Open HelloPhotoshop and close it 10 times
7) Memory consumption: 155 840 - 5,574 MB per one close/open
Maybe a garbage collector is expected to run and free this memory, but it never happened in my case. The memory pool was increasing to 1 GB when I was working with one of my panels - with no documents open in Photoshop
In InDesign I tried the same thing with HelloInDesign ( I had to close the panel completely and then open with Window | Extensions | HelloInDesign)
Memory consumption on start: 118 516
Memory consumption after 10 open/close cycles: 197 516
It's 7,9 MB per one close/open
It's the simpliest panel test. When I'm using AIR libraries the memory usage is increasing a lot faster.

Better memory usage
