Not really.  The runs were clean, CPU was high and all the  
fundamentals seemed to be correct.  Was there something specific you  
were thinking of?

The primary difference there is a new Tomcat version and perhaps some  
changes to our integration.  Later on I'd like to do some profiling  
to better understand the issues but the slow down seems to be  
consistent with other performance numbers I've seen.  I think the  
Linux Journal guys did something in this space but I'd have to go  
back and look.

I'll start that process this week.  Need to get the web pages updated  
a bit as well.  Lots of little stuff to do.
