Java Performance Tuning / Jack Shirazi has some tests
in Chapter 10 (Threading).

The difference were significant for 1.2.2, 1.3.1, 1.3.1 server
and 1.4.0 but not for 1.4.0 server.

The versions indicates something about the age of book.

I would expect the difference to be small for newer JVM's.
Synchronization has been optimized.
