I didn't see it but did you do a 'uname-a" on both systems to see if one is running a PAE kernel?
No, that was not it. But I did finally track it down. There was one additional difference in the software configuration that I had forgotten about. The CentOS 5.1 system is in a different NIS domain and it has Kerberos enabled. We are going to move to an integrated NIS/AD environment to have a single sign-on for Windows and UNIX/ Linux, and I was planning to roll that out at the same time as CentOS 5.1. The performance issue went away when I used a local account to do the build, and also on another CentOS 5.1 system (on identical HW) that was bound to the old NIS domain.
Needless to say, we can not roll out CentOS 5.1 in the new NIS domain. I will be talking to the corporate IT folks tomorrow to track down what is causing this issue.
Thanks for all the help, Alfred
