Subject RE: Heads-up / opinions? - BCEL -> tt-bytecode
Date Wed, 20 Feb 2002 15:13:43 GMT
HI!

I tested the latest build and the tt-bytecode library seems to be extremely slow. It takes
about 30 seconds to read information from some bigger classes on my machine (500 MHz). During
this time, java.exe consumes all available CPU time. 

This wasn't the case with bcel.

The class was compiled with fastjavac from NetBeans and the program runs with JDK 1.4.

Anyone else seen this? Should I attach an example .class file?

Regards,
Thomas
