This is Speed4j, a very simple (but fast) Java performance analysis library. It is
designed using Perf4j as a model, but hopefully avoiding the pitfalls inherent
in Perf4j's design. Also, Perf4j does not seem to be seeing a lot of development
these days...

Speed4j has a dependency on SLF4J (see http://slf4j.org), which it uses to log
its workings, but no other dependencies.

说的是这个么
