Windows 7: Installed Win7 on SSD, unusual memory performance

Installed Win7 on SSD, unusual memory performance

Hello SevenForums,

once again I am here for your help because I've noticed something pretty strange.
Well last week I finally decided to get rid of my old (and dieing, bad sectors) hdd and install windows 7 on a brand new SSD. Everything is fine, installed applications and updates etc.
But I've noticed something wierd, when I had Windows 7 running on the hdd, (same components) memory usage when idle would never exceed 500 mb. Now with Windows 7 on the ssd, memory usage is always above 1-1.5gb while idle, as soon as I boot into desktop memory stays fixed at 1gb with harderly any applications open.
These are the tweaks to windows that I did, are any related to memory performance issues?
  • Turned off hibernation, indexing on ssd & defragmention.
  • Moved User Document folders to hdd.

I have noticed one process "audiobg.exe" that uses 15mb ram and I can't get rid of it, tried searching online and its not "enhance audio" because I don't have the option.

And while I'm here, to minimize SSD's read/writes, I tried to move AppData folder following some steps from a guide, changing Environment Variables of TEMP and System Temp to another drive, but it doesn't seem to work for all applications, is there anything else I must do?

Edit: Just realised I should post some pc specs and tests, one moment.

Welcome to Windows Seven Forums.

To avoid a lot of Q & A about your hardware and OS configuration, please click on this link to
Edit System Specs

Filling this out, at least partially, will save a lot of time. Another advantage is when posting a new problem, the person answering can just click the My System Specs link in the bottom of your post. No need to search for the information.

If you have multiple systems just indicate that in the System Specs so that we know why many of the fields are blank.

=============================================

I would check out one of those guides for more efficiently using SSD the OS is hosted on. Things like disable process prefetch. You are not loading off a slow HD so prefetching has limited value. You can set Superfetch to only cache boot files. This should encourage the OS to have more ram free. But the system is really designed to fill up ram with what it thinks you might use. So it's not a problem unless you notice a performance hit.

I posted the template about filling in system specs because it's much better to use the form designed for it at the link. If you post 3 months from now nobody is going to search for this thread to get your specs when there's a link at the bottom left of all your posts.

btw if you run most of your applications off other drives then it's probably still beneficial to enable Superfetch for applications. I think it's all or nothing. I don't know of a setting to exclude a disk. But you never know with the thousands of Windows registry hacks/tweaks.

Prefetch is disabled but I left superfetch on, (Following the guide Sean's Windows 7 Install & Optimization Guide for SSDs & HDDs, but reading comments saying that superfetch is still usefull since applications will be running on secondary drives)
Now I'm not experiencing a performance hit, It's just worring to see 1.5-1.8gb ram usage all the time, when before the ssd, it wouldn't exceed 500mb..

How about posting a screen shot of Task Manager Resource Monitor. Where it shows the color bar of memory usage. Or RamMap by SysInternals. Often on Windows 7 mine only shows a few MB free, but a GB on Standby. The Standby fluctuates. Like if I do a video mux the free will be practically zero and the RamMap will show nearly all memory occupied by a memory mapped file from the muxing. After a while it levels back out.

Linux switched to this like 10 years ago or more. I ran top command and freaked out because it showed all my memory used. But it was just pre-fetching based on past usage.

Depending what you run, you are kind of one the cusp with 4 GB. On my 2 GB machine I run a swap and enabled pre-fetch. On my Vista PC I have 8 GB only cache boot files and run no swap. Often I have 3.5 GB free on the Vista machine. But Windows 7 fetches better than Vista.

So I'd say the short answer is, if you have to look through a microscope for a problem, you may not have one.

So I opened res manager and left it open for a minute before taking a snapshot, these are the results.

I didn't realize Comodo used so much resources, will have to look at its settings.

I think it's more a matter of personal preference. For me, that kind of free memory would make me happy.
Some other members here are trying to get the system to pre-fetch as much as possible. As long as you can't detect any glitches, it's a matter of philosophy. You can play with the Superfetch. Windows is famous for not documenting things. If you look at the tutorial for setting Superfetch to only cached boot files, it says to set on Reg key to 2 and the other to 1 (enabled) but I notice when Windows installs itself, the default is both set to 3. After playing around I've come to the conclusion you really need to set both to the same number or nothing really happens. You'll see what I mean if you read the tutorial.

See my comment and the article above it here
