I am getting more and more frustrated by the performance of NetView java processes on AIX (currently at 5.1 ML03). The new servmon daemon in NV 7.1.4 is another one - we now have jetty, maptreeserver, snmpserver and servmon all implemeted in java. If I also run ITM and TEC, I have a java dmunix process and a TEC Console java process. It now takes something like 5 minutes after an ovstart before all these java processes have stopped blowing away my CPU. Once things are running, performance of the box is fine (until I start up another java app like the Web Security Console.)

Another niggle is that on AIX, if I use ps -ef, I get HHUUUUUGGGGGGGGEEEEEEEEEE long parameter strings to the basic java process for each java daemon. Both the Sun and Windows NetViews (not checked Linux recently) seem to run java daemons from something called spmsur,( for which I can find no documentation at all), and it doesn't seem to exist on an AIX NetView. At least with this I don't get a ps entry that is 15 lines long! My gut feel is that performance is better of java on these 2 platforms too.

Anyone have insight on spmsur?
Anyone have good ideas for tuning all the AIX java processes (Oliver sent some general AIX Java tuning hints months back but they don't seem to have bought me much). Anyone untroubled by the performance of Java on AIX (aka how much horsepower do I need to have???)

Cheers,
Jane
