In this case, you are right, it might be the caching scheme used in
Jigsw. What really happens is that resources are restored from .jigidx
files on demand, so when you launch the server, nearly all hits will
trigger some resource restoring. Then, once the most accessed resource
set is in memory, everything should become really fast.

BTW: Jigsaw doesn't cache file content in memory, I might write a
filter (if time allows) that would do such a caching. You would then
plug it on highly accessed directories (such as /icons), to make some
of the resource content cached in the given area...

Anselm.
