Bruce Eckel on his book "Thinking in Java" states that a simple method call
(no parameters) takes 5.9 units of time while a synchronized method call
takes
570. OTOH, object creation takes 980 which makes it an even worse
alternative.
(The used time unit is the time spent to perform a local assignment.)
The book can be found on line (pdf format) from:
http://www.bruceeckel.com/
You can find this data on a table in "Apendix D: Performance".
Have fun,
