[Samba] cpu load on centOS 4.4

[Jason Baker]

Deno,
I had a similar problem when I installed our new servers a couple months 
ago. I'm running 3Ware 9550SX-4LP (SATA) cards in CentOS 4 boxes. I had 
absolutely horrible performance and tried everything I could to get it 
working better. Finally I discovered that I had the on-board caching 
turned off on the cards, because they don't have the on-board battery 
backup. My entire system is on a battery backup, so I figured I'd give 
it a shot. My speeds went through the roof. Now the server is what I 
would consider "normal", even copying large files doesn't slow things 
down. I would check and see if your cards have any time of on-board 
caching and enable it. Good luck.
