Benchmark: Dell/Perc 6, 8 disk RAID 10

I just received a new server and thought benchmarks would be interesting. I think this looks pretty good, but maybe there are some suggestions about the configuration file. This is a web app, a mix of read/write, where writes tend to be "insert into ... (select ...)" where the resulting insert is on the order of 100 to 10K rows of two integers. An external process also uses a LOT of CPU power along with each query.

Thanks,
Craig

Configuration:
Dell 2950
8 CPU (Intel 2GHz Xeon)
8 GB memory
Dell Perc 6i with battery-backed cache
RAID 10 of 8x 146GB SAS 10K 2.5" disks

Everything (OS, WAL and databases) are on the one RAID array.

Diffs from original configuration:

max_connections = 1000
shared_buffers = 400MB
work_mem = 256MB
max_fsm_pages = 1000000
max_fsm_relations = 5000
wal_buffers = 256kB
effective_cache_size = 4GB

Bonnie output (slightly reformatted)
