This project is a playground to familiarize myself with Google's Go programming language. The idea is to benchmark different Set implementation.
I wrote a blog post that explains all of this: http://openmymind.net/2011/7/15/Learning-Go-By-Benchmarking-Set-Implementation
There are 3 set implementations available. Modify the Makefile to include one of the implementation, remove the other lines (you can't have comments within a list like that) and then run gotest -bench=. -memprofile=mem.out. Then, pick a different implementation, run make clean then re-run the test.
