Re: FYI , Intel CC and PostgreSQL , benchmark by pgsql

It would be interesting to see the results if you do this test again with :

- scaling factor somewhere in the 100->300 range (so the generated db ~=
your ram amount)
- number of clients somewhere in 10->100
- number of transactions somewhere in 1000->1000

best wishes

Mark

P.s - Are you using the GENERIC kernel or have you built you own (e.g
with SMP suppport for your hyperthreaded cpu?)
