Cott,

I agree with you. Unfortunately, I am not the developer of the
application. The vendor uses ProIV which connects via ODBC. The vendor
could certain do some tuning and create more indexes where applicable. I
am encouraging the vendor to take a more active role and we work
together on this.

With hardware tuning, I am sure we can do better than 35Mb per sec. Also
moving the top 3 or 5 tables and indexes to their own slice of a RAID10
and moving pg_xlog to its own drive will help too.

Since you asked about tuned settings, here's what we're using:

kernel.shmmax = 1073741824
shared_buffers = 10000
sort_mem = 8192
vacuum_mem = 65536
effective_cache_size = 65536
