Interesting. I'm running on a multi-core Windows box here, and if anything we see the opposite effect. However, our scripts are all quite simple, so I suspect the total is probably dominated by startup time rather than actual processing time with both tools. For us, it's the difference between a mildly irritating second or two vs. hardly noticeable at all, not the tens of seconds for the project you were looking at there.
