jsound / MixedRandomListRealWorld_GarbageProducer
Created Apr 10, 2014
GC benchmark similar to MixedRandomList but with CPU usage < 100% and with reasonable GC rate

/**
* GC benchmark producing a mix of lifetime=0 and lifetime>0 objects which are kept in randomly updated lists.
* It is very similar to MixedRandomList: https://gist.github.com/jsound/8096954#file-mixedrandomlist_garbageproducer
* but with two changes to make it more real-world:
* 1. CPU usage is reduced by adding some latency using Thread.sleep()

A simple GC micro benchmark that creates only objects of 0 lifetime (but as many of them as possible)
