Running jrgm's tests on with a nightly build from 03-26-2001 (new imagelib and 
new cache on) on WindowsNT4, the inital page loads are much slower than 
previous builds.

Running a build from 03-26-2001 (new cache and imagelib) compared to the same 
build with HTTP using the old cache (effectivly making no one use the new disk 
cache) shows the initial page load times being signifigantly faster (usually 
between 200 and 400ms).

Darin suggested that this is likely due to Windows file system being slow and 
since the new disk cache is opening twice as many files for writing, that this 
is kicking our ass.

We are moving to a model where metadata will be stored in a simple flat file, 
which should alleviate much of these problems.
