Performance

A Java logging framework should be effective but low fuss. There are many to choose from - some would say too many perhaps. What is needed is something that is simple, productive, reliable and with good performance. SLF4J is a façade for logging in Java that achieves best-of-breed capability and plays nicely with pre-existing frameworks.

Google's Go language combines the development speed of working in a dynamic language like Python with the performance and safety of a compiled language like C or C++. It is not like Java and it doesn't aim to be like Java. Rather, think of it as C++ for the 21st century. No ... correct that - it's a bit more than C++ but yet rather a lot less than C++. Maybe better to think of it as C done right. Its headline claims are that it is fast, safe, concurrent, fun and open source.
