WAS 5.1 Express Performance

Anyone have any thoughts or know of any good resources on fine tuning WAS 
5.1 Express Application server performance?

I am running iSeries for Web on a small partition here, in my config for 
iSeries for Web I am redirecting to another AS400 off site. It just seems 
to run a little bit slow for our folks in the field. Is there anything I 
can do to fine tune the performance? Would throwing more resources at my 
partition do any good? The performance doesn't seem to take a hit on the 
400 partition except when starting or stopping an instance. I hate buy 
more memory or allocate more only to infd out it doesn't do me any good.

Any thoughts??
