Advanced Memory Management, XP/2003/Vista/7, & virtuals
article #295, updated 2493 days ago

Start reading here:

and try /3GB and/or /PAE (search for it in the above) if you’re on XP or 2003. If you’re on Vista or 7, go here:

and try PAE and very possibly IncreaseUserVA.

I have found very good performance of 32-bit Windows as virtual guest, in a VirtualBox environment hosted on 32-bit Fedora 14 Linux, using the PAE kernel on Linux and /PAE (or BCDEdit /SET PAE) in the virtual. If you use PAE in the kernel, do make sure to use PAE in the virtual, or there will be an extra and expensive memory processing step required at all times. This is to be done even if the virtual is configured with smallish RAM, e.g., 1G.

Free memory optimizer
article #142, updated 2902 days ago

Cleanmem is extremely simple in design, but shockingly good in result.

It’s helping a whole lot on this 2G-RAM Windows 7 box, and reportedly does very well with low-RAM situations too.  Windows 2000 and newer.
