What is the CPU load like? Are you at 100%? If so a second CPU may help. If you are blocked on i/o it should not use much CPU, so my guess is your CPU load is very low, and a second CPU won't do much. How much RAM do you have? Are you swapping?

Leach Sent: Thursday, July 22, 2004 12:29 PM To: linux-raid@xxxxxxxxxxxxxxx Subject: I/O Blocking Hi, Both the RAID (Promise SuperTrak 6000) or the USB subsystems really drive the system load up. I'm using a AMD 3200+ system that is only a few months old with the 2.4.25 kernel. When the I/O systems are blocking the system is very unresponsive. Some times samba will timeout, or I'll wait several seconds for commands like df, top, w and so on. I am wondering if I were to use a dual CPU system, would this solve my I/O blocking problem? Would one CPU tend to the I/O subsystem and the second would deal with other system requests I (samba, DB, LDAP, ...)? - To unsubscribe from this list: send the line "unsubscribe linux-raid" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html - To unsubscribe from this list: send the line "unsubscribe linux-raid" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
