Being a cachemaster (well formerly at least). I had 30GB of disk space
on U160 SCSI 5 Channel Raid controller using RAID 5 and LVM.
I used ext3 with no ATIME being updated.
@30GB of cache, it needs ~ 1GB for the hot-indexing of the cache.
I also devoted 1GB of Memory for Hot-Serving of cache items. My maximum
object size was 120MB or just about the size of most Large patch sets
from Microsoft, Novell, IBM, etc...
This particular cache served ~2200 users concurrently... had an average
cache hit rate of 40%... which meant ~ 40% saving in bandwidth
requirements. So at the 10Mbit/sec pipe we had... it "felt like" ~
This cached HTTP and FTP. It helped out tremendously.
