you might also try disabling search functions as well...
however, of note here, is the server drivers for raid cards are almost always better imo. i use the 2008 R2 drivers with my 9260, all the time, everytime, even though i am running win7. you might try reinstalling win7 and using the server drivers anyway, several others with this controller also get better results this way. i wish you had a non-nf board handy so you could slap that 9260 on there and check it out. once you see the difference you would RMA that board STAT. night and day difference.
the high IOPS you are receiving may be nice, but what of the latency of those??? that is where you are getting killed. you might try running one of Gullars profiles that we ran to compare fastpath performance, then he will compare the IOPS/AccessTime against other single card results with these controllers, giving you a frame of reference on the acccesstime performance.
also your chipset drivers are bound to help, at least some, i would recommend you try putting those to use as well.
These comparisone here of iops/accesstime is quite ingenious and definitely denotes the QOS within the storage system, so i believe it would be there that the issue becomes more glaring. http://www.xtremesystems.org/forums/...&postcount=185
