Dell server performance

I know this topic has been discussed before, but I'm having performance
issues and was hoping for some help. I would like some advise and
suggestions about tuning a PowerEdge 6450 (4 CPU) with a PERC 3/DC in a RAID
5 configuration. This server is housing our VMware based development
environment. It works well most of the time, but it slow. I am attempting
to determine slow points and address them.
My biggest bottleneck seems to be disk. Was there any resolution to
the disk performance discussions of a couple of weeks ago?
Any ideas what to watch? What to articles to read? Benchmark
Currently, my plan is to upgrade to Redhat 7.2 with the latest
kernel. I am on kernel-2.4.3-6. It has the megaraid driver v1.14g-ac2.
This driver is quite old. I am also going to upgrade the PERC firmware from
1.57 to 161J. The docs for 161J mention "Performance Enhancements".
I'm looking at CPU performance, disk, and network. The machines
have 4 GBs of RAM and don't appear to be swapping at all. I'm considering
breaking the RAID 5 set, restripping, and possibly going RAID 1.
Thanks for any advise you can spare,
