Good point. I plan to switch to 7.0, though the system is running the ULE scheduler. The cpu's are amd64. I tested early on with bonnie++ and was getting similar numbers to the application test. It's a good idea to try it again so I will. The RAID is a RAID 6 as the application calls for data

Good point about the RAID. It is set for RAID 5 as the data is supposed to be protected. Interestingly enough, diskinfo is telling me that the drive throughput is 175MB/s. I'm guessing that this means diskinfo is a mixture of reads and writes? Thanks Chuck Swiger wrote: > On Oct 23, 2008, at 8
