As Archie Cobbs told you, your results are closer to linear than it
seems.  The start-up time of the VM and the JIT compilation are quite
long...

You might want to take a look at the program I wrote to time various
Java bytecodes, such as method invocation, field and array operations.
It is distributed with Guaraná
(http://www.dcc.unicamp.br/~oliva/guarana/) since release 1.4.1.
There's a technical report describing the results I've obtained.

Cheers,
