Included below is the full general info from that previous post. What's
the 10000 above? His 7mb of free blocks plus ~3mb for the squid
process?
If I take 226629 - 96695 - 12000, I get 117934KB. If I ignore ICP,
117934KB * 1024 bytes/KB / 3197449 http reqs = 37.8 bytes/req
Hmm...looks like a pattern emerging. The numbers don't work out similarly
for my smaller cache though. The little one was just setup late last week
though, so really it's too soon to say it has the leak problem.
