Hello, Currently we're migrating our static node cluster from 32bit OpenSuse 10.3 using the disk_cache_module on a 2G tmpfs to a 64bit CentOS 5.3 using the disk_cache module on a 9G tmpfs. After pushing these CentOS nodes into production (and consequently adding many more requests) we started seeing a load spike on these systems. Preliminary tests have shown that using a 2G (maybe 3G - still testing that one) tmpfs on the same CentOS node doesn't have the same high load. I'm not sure if this is a bug with tmpfs, Apache/disk_cache, CentOS, or what. Any insight into this strange problem would be appreciated.
Thanks, Matt
