Solved Determining virtual memory usage & load balancing

1. Is there a command in Windows 7 (or even earlier versions of Windows) that will tell you how much of the total Windows paging file is being used? For example, you might have a total of 10,000MB of virtual memory, but 7000MB might only be used. The Advanced Settings tab under Computer Properties only tells you the total amount of virtual memory you have, but not how much of it is actually being used.
2. If you have multiple internal hard disks, and you decide to spread the virtual memory workload around, you would create a small amount of paging file in several of those drives. So for example, if you have 4GB of RAM and 4 drives, you might give each drive a minimum of 1GB each. My question is how does Windows make use of each of those separate paging files? Does it do it sequentially, where it uses up all of the space in first drive's paging file, and then uses up the second drive's paging file, etc.? Or does it do it simultaneously, where it uses each file in each drive simultaneously, allocating them in some sort of round-robin fashion?

I would not recommend spreading paging files over multiple drives. While it may be faster assuming that Windows uses each in parallel, I have seen it cause systems to stop working correctly, and it can interfere with .dmp files being created for analysis if you have any blue screen crashes.

Thanks for the tip on saving the settings.

Regarding the memory dumps, I usually only save the mini-dumps which are only 128KB, rather than the full memory dumps. I think a mini-dump will easily fit into any of the multiple page files, without having to go across drives.

I leave it alone, even on two of my three systems that have SSDs. The point of an SSD is to be a faster drive than HDDs, right? So I don't understand the rationale behind using SSDs for as little as possible.
