I have the same controller on Centos 5.
Did you try to active Cache on 3ware?
[17:56:04 root@backup ~]# lspci | grep 3ware
01:00.0 RAID bus controller: 3ware Inc 9650SE SATA-II RAID PCIe (rev 01)
[17:56:11 root@backup ~]# tw_cli /c4 show
Unit UnitType Status %RCmpl %V/I/M Stripe Size(GB) Cache
AVrfy
------------------------------------------------------------------------------
u0 RAID-5 OK - - 64K 5587.9 RiW
ON
In the past I had a scenario where I started with Cache OFF and had a
poor performance, specially for write. After set Cache RiW I got better
performance.
I didn't test that controller on CentOS 6, but is good to know if there
is some problem, because my company sells equipment with that controller.
