Each "hit" results in 5 NFS operations.

I'm sitting here pounding my head trying to understand the "5".

V3 might yield:

LOOKUP ACCESS READ

Per page hit. Is average object size 8 - 12KB? So one read on V3? I assume Apache front ends are not "browsing" they're firing names at the filer. Etc.

It has to be even more on the average. First you'd have to deal with pathname translations, which would be stored in a file somewhere on the filer that would have to be accessed first. I suppose it might keep those in memory, so it doesn't have to read that file with every hit, but you also have other files that govern access control potentially for each directory. Then your web server will probably also log each hit, and since that log file is going to get big you're going to be putting that on the filer as well. And I'm sure there must be more. It all depends on exactly what the web server has to handle when doing a hit. There may even be temp files involved that are created and deleted. Bottom-line is I would expect a hit to yield, say, 10 ops, but remember the average page has many objects all of which have to be open and read, although they may not be all logged.
