Java Performance

Java Performance Tuning by Jack Shirazi is an excellent book - ok I have only read the first 100 pages or so. It's the first book I've read for a while that contains some interesting geeky performance/jvm internal stuff. There is also the well known web site that supports the book.

The Java GC Portal article provides a nice utility to mine the verbose:gc logs, as does Ken Gottry's AWK script.

The is a load of information in Improving Java Application Performance and Scalability by Reducing Garbage Collection Times and Sizing Memory Using JDK 1.4.1

With regards J2SE 1.5, I mean J2SE 5.0 (why did they leave the 2 in J2SE ?), it would be nice to get some idea of how they managed to get the improvements in startup time and memory footprint.

JFluid appears to be moving along nicely
