Performance Problem

[ponetguy2]

Hello again everyone. I have three Solaris 9 servers (
SunOS hostname 5.9 Generic_118558-27 sun4u sparc SUNW,Sun-Fire-480R). All three are currently non-production boxes. I installed the latest and greatest Solaris 9 patch cluster on all three at roughly thesame time in single user mode. During this install process, I noticed that there was a significant difference on how long it took to completely install the patch cluster on box A. Box C and B took alot longer to finish (roughly 5 to 10 minutes) vs. box A.

I ran some test and found very little CPU load on all three when installing patches. However, there was a slight higher iowait load on box B and C vs. A. Despite of the iowait difference, I don't think it should cause much of a difference in performance.

Should I run format>analyze>test on all three?

Any suggestions on how to attack this problem would be greatly appreciated.

Sorry Annihilannic, I realized that and was hoping you wouldn't take offense to my hard-edged post.

You have answered my questions before and I appreciate your help.

My apologies for my "attitude.

I'd say it's not for you.

btw, do you have any solid performance numbers for all of the drives on each server? Just wondering if you are driving yourself nuts for little gain.

I agree with you kHz. I'm just following orders

Personally, I think it should'nt be much of a problem. However, I do understand why it would cause a concern.

iowait on the problem servers (box b and c)are at 25% when I unzip a file. box a's iowait is at 10 to 15% when I unzip a file. It seems that write is very slow on box b and c and i do notice the difference on how long it takes when i uncompress files.
