[PJUG Javamail] Optimizing Java

[Joe Hoffman]

Vincent,

You bring up some good points.  There are many improvements in  
optimization in more recent VMs.  However keep in mind that most of  
the inefficiencies that exist in software are the result of  
improperly  architected and written applications, not something that  
the VM can do much about during compilation and execution time.

Optimization is such a broad topic, despite first appearance.  This is  
particularly true for Server side applications where a pool of worker  
threads are contending for the same resources and working together in  
a complex  dynamic model.  For this reason it can be quite challenging  
to find the root cause of these types of problems.

I am doing a talk at the October 20th meeting on this very topic,  
specifically performance tuning of Server side java.  Perhaps you can  
bring your thoughts and observations to this presentation and help  
make it a great evening of discussion.  I plan to explain some of the  
common challenges and how to find the root cause of these types of  
problems.

I'm looking forward to your contribution.
