I've been playing with a new Linux server and a raid system with a couple big (100GB) logical volumes, and after reading the AIC7XXX driver documentation i wondered how some of the commands could really affect performance on a loaded server. Does anyone have experience tuning those parameters? For instance, i believe that enabling tagged queueing on each device (now its disabled by default) to a value like 32 could be a good idea, but dont know about side effects, of it it is worth it. Anyone has real data on it? Pedro Rodrigues To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe aic7xxx" in the body of the message
