Youngstown State University is trying to implement university-wide email using Linux for S/390 under VM/ESA. As part of this, we were hoping to use IMP as the web mail application. However, response time is awful. We are running a IBM 9672-R42 (generation 2) machine. Is this the problem? I can't believe that IMP requires that much CPU. Maybe I'm wrong. Upgrading the processor is not a current option. Moving it to a Intel, RS/6000, Sun, etc. is an option. I personally would like to see it run (successfully) on S/390. Any suggestion on how to improve performance or even determine where the bottleneck exists that is causing the problem. I'm a Linux newbie, really just an occasional user. I'm not the one installing and implementing it so I have no idea where to turn to get guidance on this.
