Here is my new pgbench's point

pgbench -h 127.0.0.1 -p 9999 -U postgres -c 200 -t 100 -s 10 pgbench

I have server computer install Windows 2008R2, PostgreSQL 9.0.1 64 bit, 8G RAM, RAID 10 - 4 disks

Is it common pgbench 's point with my server ?

Thanks you very much.

You really should replace "-t 10" with something like "-T 60" or more.
