SBR600 Lab 2 - Playing with the -J option

Today, i found that the rpmmacros file controls how many jobs make will start. So i did some playing around below are my results.

I was a little surprised that 4 was the fastest time as i am running a duel core system. I did not automate this process, but if i did im sure the process would of been a bit faster. I tried to run these tests with my system doing as little as possible to make it a fair test, but without running the test hundreds of times and with different builds its hard to say if 4 is the best result for everything. What seems to affect the results are what the build is waiting for CPU , or disk as well.
