[CS4] About ram usage
Setup:
Sager NP8760 CPU i7 Q820 1.73ghz both cores - RAM: Ram: 8192MB DDR3 1333 (2 DIMMS)
Vid card: ATI MR HD 5870 (1 GB)
Running Win7 64bit home prem
Using AE CS4.
I see this information on the bottom of the `Render que' when rendering footage.
RAM: %60 used of 4GB
But I have 8 GB of ram installed. So how can I tell if AE is seeing it... or is this info telling me it is not.

Questions about mpd and sonata ram usage
Hi again!
I'm very impressed with mpd and i really love the sonata client with it's cover art , lyrics fetching features .
I've noticed that mpd uses about 13 mb ram and sonata 16 mb of ram. I have about 6 albums in my library .
I was just wondering if it is normal for mpd and sonata to use that ram .
I have enough ram about 1gb so it's not an issue , i'm just curious if this is normal
Also i've noticed that with mpd and sonata the cpu usage is much lower than with audacious when playing files , but the ram usage with mpd is higher
Thanks again
Last edited by shak (2010-06-10 12:15:25)Hmmm...I have Arch64 with a 15,000 collection, MPD uses 9.8MB and Sonata uses 52.5.MB, whether there are songs in the playlist or not.

i would like to understand the relationship between scratch disks and RAM usage in Photoshop.
While i was working on a fairly big psb file (2gb), photoshop kept prompting that I was out of memory, but in fact the utilization was only 75% (i had 16gbs total, photoshop was only using 7gb, and i allowed PS to use up to 14gb in total). when it says out of memory, it was actually my scratch disk at fault ( i only set 1 scratch disk, which was my 120gb SSD running out of space).
any idea how I can optimize PS to use up all my RAM first before even touching my scratch disk? (short of using a RAMdisk, please).
thanks!I am curious about this also. I just reinstalled W-7--have 11 G of physical memory--a ton of hard drive empty space also, and I have been wondering why PS_CC is so slow--since basically I have only put my Security and Browser in addition to Adobe back on the Dell XPS computer..... At least now it does show the downloading percentage (like .psd file) , but that must be what is happening. I do think that some of these "frozen" screens I have been experiencing, was because the program was using scratch disk, instead of the Ram... I came up from CS-5, and can't describe it in detail, but just realize how slow PS-CC is in most everything. Going back and see if reallocating will help...

High RAM usage when system is 'idle' (EtreCheck)
Hey guys,
First timer here. Ok here's my question :
I recently bought a secondhand Macbook pro 15 inch. For me it's a huge upgrade coming from a 2009 13 inch Macbook pro. Because a friend of mine wants to buy my old one I was doing some diagnostics on the 13 inch, which has 4 GB of RAM, and found out it had a lot of inactive RAM usage and wired usage, almost 2 GB, due to a lot of launchdaemons etc which were hogging the RAM. I used terminal to kill these agents and deamons and now that system is running smooth again. Maybe it's wise to mention that the 13 inch runs on ML.
3 days ago I did a clean Yosemite install on the 15 inch, swapped the HDD for a SSD. And already the activity monitor shows a whopping 4,28 GB of RAM usage while I'm typing this with just safari open. I thought I could do the same trick as I did with my 13 inch but it didn't help, had some java deamons and helpers and deleted those. In terminal I looked up everything via launchctl list and there's nothing unusual going on as far as I can see. I had VirtualBox for one day but uninstalled it using their uninstaller. I have no clue what's eating all this RAM. Please help me out so I can be a proud owner of my second macbook for atleast 5 years to come. Thanks in advance.

The page outs indicate the OS has not recently swapped any memory to disk.
Apple made changes to 10.9 that are the same on 10.10. Memory will be used as much as possible. It is the fastest storage on the system, keeping it free is a waste of your time - data loads fastest from RAM.
This is a good explanation…
http://arstechnica.com/apple/2013/10/os-x-10-9/17/#compressed-memory
The system also frees 'cache' memory when another process has more need to use it. Eventually it will swap to disk (which is slow) so the OS also compresses memory before swapping is needed.
Please avoid killing launchd jobs, many will simply restart or relaunch again later. Eventually you may kill one that hangs the OS & corrupts the disk via a forced shutdown.
I do suspect you may see issues when RAM does get low, but there is no evidence of that here. The memory pressure graph will show red when swapping - every other colour is fine. Wait until you see red & then note the top memory users.
If you don't want java installed you need to find removal instructions & get it all off the system, simply stopping the update checks will leave Java in an old state - terrible for security.
Also do you know what 'Live' is? It crashed recently, if it keeps doing that it may be worth a look, however it may just be one if the things that was effects by the killing spree -
Why does closing all open windows (15) and leaving only one drop ram usage by only 100mb from 1.5 to 1.4Gb.
What is in this 1.4 gb ?
I don't care much about ram, It's just that cpu usage spike like crazy by the end.
''Edited to remove swearing - TonyE''Hi musicfan,<br />Sorry you are having problems with Firefox. Maybe you should have asked earlier and we could have fixed it.
Reading your comments I do not see that rolling back to an insecure Firefox 22 will actually help you much. You are probably best using IE, unless you have also damaged that.
*[[Export bookmarks to Internet Explorer]]
You should not use old versions they are insecure. Security fixes are publicised and exploitable.
* [[Install an older version of Firefox]]

Most others will not be having such problems. We are now able to say that with confidence because after developers missed a regression in Firefox 4 telemetry was introduced so that data was obtained. It may be an idea to turn on your telemetry, if you have not already done so, and decide to stick with Firefox.

High kernel_task RAM Usage in Yosemite 10.10.1
Hello All,
No matter what I'm running, I always have high RAM usage with kernel_task. I've looked around the other threads and never found a definitive solution. I wouldn't call it crippling to my system but I would like to resolve the issue. Below is a screenshot of my activity monitor, and my Etrecheck run. Please let me know anything I can do to reduce the RAM usage of this process.

Well, i've got my 13' Macbook Air today (4gb ram), and love it.
The only thing that bothers me is the extremely high ram usage of Lion, when i turn the Macbook on it jumps to about 1.3gb ram usage which i find really much considering my PC running Windows 7 uses less.
After some casual usage it even jumps up to about 2 gb ram usage.
Is this normal? how are the other Air's with only 2gb of ram handling this? there can't be much left there, besides just running the operating system.
i am new to Mac's so am i doing something wrong?Hi all,
After last Lion update a i seem to encounter a very strange situation regarding ram usage.
I have an early 13' mbp core i5 with 8gb of ram.
After upgrading to lion 10.7.1 i have less than 500mb available after just a few hours since i turn it on.
I must mention that the only running apps are: safari, mail, app store, ichat, ms excell and itunes.
Upon quitting excell, itunes, appstore and restarting mail and safari i still only get 1,5gb of free ram.
My suspicion is that there is another ram leak somewhere, or else i can't explain why my computer user 128mb of swap with 8gb of ram installed. -
I'm just wondering what's up with the RAM usage on my macbook. Right when I start up 500MB of RAM is being used (wired and active), 100MB of it being the kernel task. After a typical session of use, I close all programs and find that the RAM usage is about 800MB and the kernel task is using 250MB. Just wondering why the kernel task's RAM usage creeps up like that and doesn't go back down. It's just a little perplexing to have the same exact programs running and be down 300MB of free RAM.
I was having the same problem and looked into it, this may help:

im using htop
im install xubuntu to comare them.xubuntu show me ~220mb ram WTF???
and I compare htop logs of them
in xubuntu:
panel plugins(like language layouts,cpu load...) using about 10mb each.
X using about ~80-100mb
in arch:
p.p. using about 20mb each
X using about 40-60mb of ram.
when i will be at home i'll paste screens of htop on xubuntu and arch

I am looking for some tips or best practices to get the most efficient use out of my RAM, particularly when it comes to the OS. I have a Latitude E6530 with 16GB of RAM. I started out with 4, then went to 8GB, then to 16. I run the same number of programs
in my daily routine, yet it seems that the more RAM I install, the more the OS gobbles it up. Since I run the same programs daily, I would not expect RAM usage to fluctuate very much and expect these apps to consume about the same daily. It seems like the
only thing that can be consuming more RAM is the OS. When I was at 4gb, I hovered around 70-80% RAM utilization, went to 8GB, same results, now at 16GB, and almost hitting that number again. I understand the OS needs a certain amount of RAM to operate, so
is there a way for me to limit what the OS takes so I can have more for programs that may need it? Will the OS "give some back" if needed to extra programs I may decide to run when I am at a high utilization mark? What I don't want to get into
though is a constant swap condition, especially with core OS components that need to stay in RAM. Whats the best way to go about this?it will be better if you start from "general" about RAM management
http://windows.microsoft.com/en-us/windows/optimize-windows-better-performance#optimize-windows-better-performance=windows-7
actually its not only based on how much RAM that you are using, but how you prevent another program or HW attached (even external graphic card or LAN card) used windows service that maybe will increase RAM usage.
You can start using Windows performance tools to investigate
http://technet.microsoft.com/en-us/library/cc749249.aspx
try to compare different condition like, a few program running during start up (clecan boot), disable security software, no other 3rd party HW attached, no internet connection, upgrade latest driver for all HW or else
my opinion, Windows will only using RAM that needed to run start up, increasing RAM usage for windows process depend on the software running and HW attached
for more details and complicated process :) , you can read and implement this with your development environment

Hi,
I've a Mac Pro 2009, 8 Core, 32 Gb Ram and GeForce GT 120 512MB.
During the render process with Motion 4 usage of ram is only 6 Gb, 24 ram Gb are always free. Is this mormal?
Thanks!More or less normal...
Motion 4 has a finite limit (about 4GB) for RAM utilization because it's not "full 64-bit". About the only place you'll see major RAM usage is with After Effects (where, if you have multiprocessing selected, you can get a bunch of tasks going at 3.2GB each...) -

In the pref file ti states that: "Note: After Effects will not use more that 2GB of RAM... See After Effects Help for information about enabling this option."
I have 4 GB ram. I have searched AE Help, Microsoft, adobe and Google, ..,. for 3 hours now. I cannot find out HOW to do this. Everyone talks about it but no one tells HOW.
I really would appreciate it if someone, anyone would be kind enough to give me a hint as to where I might fine information on HOW to do it. It is so frustrating that Adobe help files does not tell you how to find anything or use the search terms in stating that you can find something. It sure would make it easier to use their programs if they stated how. But maybe it is just that I am not a tech guru, only a lowly user.

Is there any way to 'recover' RAM usage (other than restarting)?
Hi everyone,
I just upgraded my White Macbook 4,1 to 4GB of RAM and when I first boot the system, Activity Monitor shows that over 3GB is free.
After several hours of usage (Mail, Safari 4 Beta, iTunes, iCal, iPhoto, Time Machine, Address Book, and yes...Activity Monitor!) it shows just over 2GB free.
Now the part that puzzles me is that even after quitting all these applications, the RAM usage does recover somewhat, but never reaches it's original >3GB of availability.
A reboot certainly does the job. But is there any other way that Leopard can recover this memory? Is this normal? If I simply leave the system idle for some time without any open applications will Leopard eventually reclaim the lost memory?
Thanks!
Message was edited by: Michael271There's no need for any "ram" recovery. It's all handled by the memory manager. You must be coming from the world of XP. See the following:
About OS X Memory Management and Usage
Reading system memory usage in Activity Monitor
Memory Management in Mac OS X
Performance Guidelines- Memory Management in Mac OS X
A detailed look at memory usage in OS X
Understanding top output in the Terminal
The amount of available RAM for applications is the sum of Free RAM and Inactive RAM. This will change as applications are opened and closed or change from active to inactive status. The Swap figure represents an estimate of the total amount of swap space required for VM if used, but does not necessarily indicate the actual size of the existing swap file. If you are really in need of more RAM that would be indicated by how frequently the system uses VM. If you open the Terminal and run the top command at the prompt you will find information reported on Pageins () and Pageouts (). Pageouts () is the important figure. If the value in the parentheses is 0 (zero) then OS X is not making instantaneous use of VM which means you have adequate physical RAM for the system with the applications you have loaded. If the figure in parentheses is running positive and your hard drive is constantly being used (thrashing) then you need more physical RAM. -

I'm stunned at the amount of RAM usage by LIghtroom. I have 6Gb of RAM using LR4 in 64 bit win7.
This is what happened when I opened lightroom to edit a shoot of jpgs, all of which were only about 3mb each ( I wasn't even editing 30Mb RAW files from my DSLRs )
[i]figures from task manager/performance pane[/i]:
No Lightroom
0.99 GB
Launch Lightroom and cat
1.53 GB
select next pic
2.00 Gb
select next pic (no editing yet )
2.20 GB
after editing two pics
3.13 GB
editing the 2nd pic in Nik Software Silver Efex pro 2 ( edit copy with lightroom adjustments ) and returning to lightroom
2.85 GB
but ....
Very soon, after only a few pics, the RAM usage is up to 5.5GB
This seems very disproportionate. Why for example would simply selecting another 3mb jpg eat up another 200Mb of RAM? And why after only a bit of editing on this 3mb pic in the develop module eat up another 900Mb of RAM?
The other highly annoying issue is that once Lightroom has decided to eat up nearly all my available RAM after editing only a few 3mb JPGs, things slow down rapidly. selecting another pic means everything locks up while their is vicious disk activity ( presumably swapping to swap file because Lightroom needs another 200Mb of ram for just one 3mb JPG )
it's not much fun having to quit LR every few images just to 'reset' thje amount of RAM.OK, seem to be getting somewhere now
As stated in the OP I work in 64 bit Win 7. I have a win 7 32 bitpartition on the same machine I use for various things and also for testing Lightroom updates without upsetting my main LR work partition.
Earlier tonight I isntalled 4.1RC2 on my win 7 32 bit partition and ahve been working on a shoot. Interestingly the RAN usage seems much better managed. Instead of progressviely creeping up to a point of ARRGHHH!!!, with RC2 memory is released when switching images. Great news!! Now bearing mind I still need to stest this in my 64 bit martition and I will isntall RC2 once confident it wont' fall right over, but positive os far.
ALSO, which I've just started testing is the negative cache disablement as described by Adfoibe Employee Julie Kmoch here

Here's an update on what changed in RC2 relative to Develop performance.
For starters, in RC1 we experimented with turning off sharpening while sliders were moving. We got a fair amount of negative feedback on that, and have reverted that behavior. Instead, we moved more of the rendering to a background thread, which keeps the sliders moving smoothly. One caveat with the behavior in RC2 is that those background renders can pile up if you're moving fast. The final 4.1 release will do a better job of trimming these when possible.
I worked with a number of you who volunteered to try an experiment a couple weeks ago that turned off something we call negative caching. The results were mixed; a couple people said it was a clear improvement, others didn't see a benefit. But I'll offer it here in case it helps others who find performance starts out reasonably then suddenly, consistently goes south until a restart.
What the following will do is turn off a cache which saves some of your most recent work done in Develop such that if you revisit a recently touched image, it loads faster. However, if our calculations are off, this cache can sometimes get too big and cause ACR to use virtual memory instead of RAM.
To try it:
1. Create a text file called “config.lua” and put the following line in it: AgNegativeCache.enabled = false
2. Launch Lightroom, go to the Preferences dialog, Presets tab, and hit “Show Lightroom Presets Folder”.
3. Close the Preferences dialog, quit Lightroom.
4. Drop the attached config.lua file into the Lightroom folder that was opened in step 2 (do not put it in one of the preset subfolders). So the path to the file will look like this:
Mac: /Users/[yourname]/Library/Application Support/Adobe/Lightroom/config.lua
Win: C:\Users\[yourname]\AppData\Roaming\Adobe\Lightroom\config.lua
You’ll know this switch to turn the cache off is working if you see the “Loading...” symbol even when you revisit the previously edited image in Develop. (When caching is on, you can often revisit a recently edited photo without the Loading warning showing.)
I'll report back laters
