Hi, I've got a testing amd64 system with two 3Ware 9500S controllers and performance with the newest kernel is dramatically slower than with 2.6.32-5-amd64. Also response to tw_cli and 3dm2 is glacial. Possibly an IRQ issue?
Anyway my question is what list is best to ask about this problem. Or should I just go ahead and file a bug report (my first)? Bonnie++ output appended.
