Apple AppleShare IP 5.0 Update - Manual (Page 19)

Here are a few things to keep in mind when considering the amount of
memory you plan to reserve for other applications:
m Use a minimum cache setting of 1 MB (the default setting); the Finder can
perform poorly (or crash) if there isn’t any free memory for it to use, so the
amount of memory reserved for other applications should always be at
least 1 MB.
m The Web & File Server cache does not attempt to claim memory used by
applications that have been opened prior to starting the Web & File Server,
or by applications that are running prior to the expansion of the Web &
File Server’s cache. So, if there are applications that you plan on using
often, consider starting them before you start the Web & File Server
program. For example, if you start a database application that has a 4 MB
memory partition before you start the Web & File Server (or before the
Web & File Server tries to expand its cache), that 4 MB does not count
toward the amount of memory reserved for other applications.
m If you think that the Web & File Server’s default cache of 1 MB is
sufficient for your file service needs, you can reserve all available RAM for
other applications. For instance, for a computer with 32 MB of RAM, you
can set the reserved value to 32 MB; the Web & File Server will not
attempt to allocate additional cache blocks.
m If you’re not planning to run many programs other than the Web & File
Server, lowering the amount of RAM reserved for other programs may
improve the performance of the Web & File Server.
