Are you paging? Do you have SRM STORBUF set higher than the default? If you are paging are you keeping the page space < 50% full and well spread over your I/O system? Does your perf monitor tell you what your servers are waiting on? How'd you size the servers virtual mem requirements and their JVM sizes? (It is a huge challenge to get server people to realize that bigger is not always better).
There's lots of areas where things might be configured less than optimally. Marcy "This message may contain confidential and/or privileged information.

Do you know how much WebSphere hits the desktop when it starts up? Maybe I am looking in the wrong closet. As always, thank you for your input. -----Original Message----- From: Linux on 390 Port [mailto:[email protected]] On Behalf Of Marcy Cortes Sent: Wednesday, May 26, 2010 1:37 PM To: [email protected] Subject: Re: zLinux / WebSphere "spinup" times Is it your ID authentication that is slow? I know ours caches things but when it has to go back to the huge Active Directory source, it can take a minute or so. How's your memory/paging/etc? Any spikes you can see on your perf reports?

Every morning when you first login to the WebSphere management console it is slow. After the initial logon response is fine. What's going on? Is something asleep? Cached out? David M.
