No its not because of standby, its because you have no page file for memory that is in use by other processes. Standby memory is not paged out to the pagefile, it is overwritten the moment it is needed. However, other processes are stuck in memory as well as "Modified" memory. Without a pagefile the Modified (orange bar) memory will grow and grow.

Ok then consider this.

Maybe the problem isn't that its on standby. Maybe its because the rate at which the pages are "released on request" is slow and that is whats causing a performance drop. I mean, I have free memory now and things are running a lot smoother. Before, when it was 0, windows always had to waste time releasing memory and giving it to the application that requested it. Still, I only have ~1.6 free. And when I run my main major java application I usually append -Xnx4g to it. Yet it still has trouble giving itself that much memory and runs slow as a result.

IMHO if you are trying to allocate ram to anything you are creating the problem. Let Windows 7 take care of the ram. If for what ever reason you run short of ram just install more ram.

But...its a server. And if I don't include that part then it will result in out of memory issues when I still have free memory..

If there is a program reporting out of memory, then that program is not compatible with windows 7

There are a couple of issues like this and the "Documents and Setings" folder that cn cause some programs to simply not function properly on W7.

If you are writing your own JAVA apps, you may need to find a different way of detecting the memory used/free. Or possibly make sure your java VM is Windows 7 compatible etc...

The Java VM should NOT be saying there is no memory. Or maybe if is says "no free ram" it also says "XXX on standby" in the same function call? The addition of the two of those is in fact the "free ram for application use".

Also, why using -Xmx4g? Are you sure setting the maximum heap size to the maximum a 32bit process can address (unless this is running in a 64bit JVM environment) is even wise? Also, is it just this particular java VM having issues on the server?

I hear that win7 will free up that standy ram when it is needed, but it doesn't for me. When i see my ram running out it will just run out my programs will lag and my standby ram stays, its driving me nuts that almost half my ram just stays in standby and never gets used. I cant unzip a file while watching a youtube video.

I have a quadcore Q9559 @ 2.83GHz with 4 gigs of ram and a 1 gig geforce gtx 560 vid card

Any ideas?

RAM has nothing to do with your problem. There are many factors to consider when having a performance issue then just RAM. Your CPU for instance could be a bottleneck, or your Graphics card, or your Hard Drive. Not every performance problem is because of RAM. The fact that Standby is unchanged means your RAM is not the problem, nothing is fully utilizing it to the need of overwriting Standby.

And you should have opened a new thread...

I don't use the Windows 7 paging file, and my modified memory does not continually grow.

Well if it isnt my ram, then why is it when my free ram reaches zero, i experience my lag issues and only then. If i have free ram i never have lag. and when it reaches zero, my comp stops what its doing, and the standby ram stays teh same, and i have to wait for my free ram for it to fix the problem.
