Umar,

maximum_object_size is more to do with how large the objects are that
you want to cache. For example in our office proxy I like to cache
microsoft service packs that are downloaded, so I have upped the
maximum_object_size to 250 MB. Since your bandwidth is probably not
going to be sufficient for delivering such large objects straight out of
memory I wouldn't worry about making the maximum_object_size_in_memory
much larger than it already is.

If you check out the archives you will see that the rule of thumb for
disk cache to memory cache is about 100:1 (if I remember correctly). So
for a 5GB disk cache you should have 50MB of memory to handle it.

Anyway that's my contribution, I'm sure others will also have something
to say about your configuration options.

Regards,
Oliver
