I think this is a balance problem. But how?

For x86 systems, limit size is 3.25G for ram. On a clean and stable Windows 7x86,

If ram is 2gb, same size of pagefile is acceptable. Blocked ram size by OS is ~400-600mb. So, ~1.5gb free ram is not a bad number for common applications also for many games.

If ram is 4gb, same size of pagefile is a lilbit fat I think. Blocked ram size is ~600-800mb. So, free ram is ~2.5gb. That's ideal for a multicore cpu and 3.25gb system. Because, ~4gb filesize is very big for 7200rpm disks if you consider read-write speed. In my opinion this system must use max 2gb pagefile.

For x64 systems, blocked ram size increases a lilbit more, but not so far.
For 4gb ram, free ram size is ~3.2gb. For 6gb ram, free ram size is ~5.1gb. For 8gb ram, free ram size is ~7gb. These ara very good numbers for an OS. And I don't think pagefile size must equalize to free ram. If you consider 16gb ram and over, working on a 16gb pagefile makes system more and more slower. Even if you have an ssd (or anything lower r-w speed than ram).

By the way, if you have free ram, decrease the size of pagefile wherever you can. Let ram do them all.

Am I wrong?
