NanoJava is an advanced optimization tool designed for Java programmers.

It provides valuable information, allowing the user to greatly improve code efficiency, and to better understand the internals of the JVM (Java Virtual Machine).

Any Java programmer has some day encountered performance problems. These problems often come from very specific portions of the code. It is then necessary to apply advanced optimization and correction to the involved code. Many tools allow to identify the critical sections of code. But only NanoJava provides efficent measures on coding variations.

NanoJava allows to measure the three effect of a code section: 

These three figures are measured for very small portions of codes, for instance the addition of two integer values.
