Hi everyone,
We currently server our entire web tree out of AFS. This includes Joomla and other PHP-based applications. While I was benchmarking our new server, I noticed that the following rough performance numbers: Static files served from AFS: ~200 requests per second Joomla home page served out of AFS: ~30 requests per second Joomla home page served from local ext3: 1000 requests per second. I'm running a 8 cores with hyperthreading (16 threads). I'm running the Apache threaded worker MPM on RHEL5.5 with mod_fcgid and OpenAFS 1.4.12.1. I have Apache configured for ~1000 threads. My data (250GB) and stat cache for the AFS client should be big enough to not have to hit the server. My afsd has the following options: " -fakestat -dynroot -chunksize 18 -stat 500000 -daemons 32 -volumes 2000 -blocks 212713128" What is recommended to improve my AFS performance for Joomla? FYI, my measurements show that the "stat" system call is run more than any other.
