Welcome to Stopwatch

Stopwatch was ment to replace System.currentTimeMillis() calls, match like Log4j replaced System.out.println() calls. To see how it does that go to Quick Start page.

Why Stopwatch

Stopwatch was inspired by ATG's performance monitor tool and to be honest, it wouldn't probably never exists if I have discovered JAMon earlier. But I didn't and I couldn't also find any good, open source, performance measurement API, that was able to measure performance of any given piece of java code. So I started writing Stopwatch. Then I thought it may be useful for other people as well and so I decided to make it public. SourceForge just seemed the right place for it.
