Dear New_trader, this is great advice. I just tried the JVM with -server switch and it roughly halfed execution time for optimization !!!
Tried a few more switches, but it roughly remained the same. Tried also JRockIT. It is significantly faster than standard -client SUN Java VM, but remains significantly slower compared to -server setting. I am not a VM guru. Perhaps someone has more advice on optimal settings. After all, optimization runs are a significant portion of work with JBT.
