[Benchmarking] Test run now

[Dane Springmeyer]

Benchmarkers -

I did some new mapnik runs last night, and uncovered (through using oprofile) that most time for mapnik was being taken up in png quantization. Somehow I accidentally enabled this, which I fixed before my runs last night, as my understanding is that we are all rendering to full color png, not reduced colors. This helps with performance quite a bit.

I am now looking to do some tests on the linux machine to look at, now with this fixed, what other factors are at play for performance.

So, if anyone needs to finish runs, please contact me on IRC and bump me off, as what I am doing is testing and is not critical if others need the machines.

Thanks,

Dane
