Server Performance,

Let me first compliment the Jazz Development team on the new Web Admin Page in M4. The Monitor page includes some wonderful information. That being said, I noticed my server is performing slower with M4. So I am looking at the monitor page and under server health, I noticed that the Server "Max Memory" is set at 256. Is this an appropriate amount? Is this my bottleneck? Is this set by Jazz or the WAS? Where should I change this?

Thanks!

Here are some details on my environment:
Redhat 5 U1 x86
WAS 6.1 Fix 13
DB2 9.5
Jazz M4

Thanks! Out of curiosity, What other performance tweaks should I be
making? Anything to the database?

256MB is not going to support much of a server. We run jazz.net with 1000 MB max memory. This is configured in WebSphere, in the Admin Console go to Application servers > server1 > Process Execution > Process Definition > Java Virtual Machine. In the "Generic JVM Arguments" where you set the teamserver.properties location, add -Xmx1024m.

That's our only recommendation so far, we do apply some settings to the DB2 database regarding the transaction logs and buffer sizes when we create the Jazz schema.
