<3C043518.BB53E142@tkg.ca> Subject: Re: Performance Degradation on New Hardware Platform Date: Mon, 3 Dec 2001 23:05:34 -0500 We have the SMP installed. To give it a benefit of doubt, we re-installed the RS506a. Also, the second NIC was phyically removed. Unfortuantely, there was still no apparent improvement. Finally, we talked to HP and have the UNIX support team told us to disable the AMI Raid Monitor (under /etc/idrc.d/amird). The system started to speed up. They said there had been known performance issue with the monitor turned on. I don't understand why they do not make it known to the customers by printing the info in the form of release notes.
Thanks for your help.
