Parallel

This is a revolution.

Behold your eyes as I unveil the new wonder of this age.

Parrallelized PSUL.

Waiting for seven hours is so passé, level up you apps with the power of parralelization !

with 6 threads, I was able to make a daily run of PSUL in 24 minutes. 

The optimal number of threads should be 8, assuming nothing else runs. 

I say that 8 is the optimal based on the rule "1 thread per core" on a completely empty server. More than that create costly context switches. 
The thing is, PSUL is not the only thing running. So I settled for 6. I'll benchmark it to et the optimal number.
