For the NT Kernal (being Win2k and XP) Microsoft recommends a maximum page file size of 1.5 times the amount of physical system RAM for systems with 512 MB RAM or less.
Though Microsoft does not recommend manually changing the page file size, numerous tweaking sources detail that the default operation of Microsoft's page file size is inadequate for optimum performance (default operation is set for allowing the most users reasonable if not good performance). The default page file size utilizes a dynamic swap file which is continually resized as determined necessary by the operating system. This continual "re-sizing" can noticeably affect the performance of program operation and file access.
Popular tweaking management of this setting is to statically configure both the page file min & max file size to 1.5 times the amount of Physical System RAM. Setting this file size statically, forces a set file size and space to be used for swap file usage - negating the need for the OS to continually resize the swap file.
More and more users running Windows XP with 512 MB of RAM or more are posting that using a ratio of 2.0 times physical system RAM or even going the other direction and completely disabling the page file/virtual memory provides an even more noticeable improvement - reasoning that all programs are completely loaded into RAM (which is faster than HD access) resulting in faster access. Neither of these last two configurations should be attempted without at least 512 MB RAM AND a willingness to reinstall your OS (read "lose data") in the event the config change is too aggressive for your system and or cannot be recovered.
*Note that the type of programs you use, and the manner in which you use them are considerable factors that may or may not work well by forcing RAM to accomodate these settings - though statically configuring the swap file to 1.5 times Sys RAM seems to be a painless and well accepted performance tweak.
**Though these tweaks are common knowledge in many geek forums, Microsoft does not encourage or support manually configuring these settings (surprise eh!? 🙂 )
It's always good though, as with any tweaking advice, do some googling - read some Microsoft, see what information you can find on your own. Everyone's hardware/software configurations are different and might not address unique issues that may be of interest to you.
Good Luck!!
