Hi, the optimal seems to match the number of CPU's available on your system, I've seen an almost 50 % performance increase running for instance 4 threads instead of 1 on our quad core machines.

Daniel Ford ---04/06/2009 07:12:12 AM---I didn't change the number of worker threads. What kinds of times are you seeing when you increase the number?

On my x3500 64 bit Ubuntu quad core 16 GB memory running the ant script takes 1:58 minutes too. Pretty good :)
