Performance of my app was not pretty...  Subsecond on green screen 5-9
seconds through WebFacing.  This was over two years ago.  WebFacing
has got better than it was then, I suspect.

Back then I found Tomcat and WAS 3.5 to be roughly similar at low
workload levels like yours.

My strong advice is to convert an application and try it.

For WAS, tweak every timeout you can find to make them outrageously
long.  I had WAS die repeatedly and it was never stable because the
machine was so burdened.  Internal WAS timeouts were tripping, and it
was not simple to figure out what to address to make it better.  IBM
pretty much won't help you with unsupported configurations, but you
can glean a lot of information from the WAS newsgroups.

Tomcat worked OK with WebFacing but it too had stability issues.  I
never ironed them all out, but I suspect they were workload related.
(We're an IBM BP, and WAS is the way to go for us.)  WHen I say
'stability' I mean that on occasions, WAS or Tomcat would stop
responding and need to be restarted.  Or they would throw an
incomprehensible message in the log file and need to be restarted.  Or
they would terminate with an incomprehensible message in the log file
and a generic message in the job log and need to be restarted.  You
get the idea.

This whole web world really wants a modern machine like an i5.
