[PJUG Javamail] [PJUG javamail] JDK 1.4 - Faster Java serialization options?

[Joe Hoffman]

Subba,

You mention that you are playing a big penalty for JDK 1.4  
serialization.  I'm curious as to why you came to that conclusion.   
Did you perform any empirical measurements?

If you haven't already done so, it might be worthwhile to  
quantitatively measure various components of your system, including  
the network latency, volume of actual data moved, marshal/unmarshal  
time, method response time, CPU time, etc.  Then just as important is  
to perform these measurements across a stairstepped load to see which  
components don't scale as our load increases.

Perhaps you've already done this,  just curious as to what you  
measured and what you found.

thanks

joe
