Those should be just pretty small files though, right? Just some analysis info or something like that, so it shouldn't really slow down the 2nd pass if they're on the same disc as the source or output files. I don't know if it even does save any other temp files. Maybe it doesn't.

They're relatively small, yes. Furthermore, reading from them and writing to them is typically done sequentially, which is sped up by the cache in your HDD, so that wouldn't be your bottleneck.

What speed problems are you having?

I work as a Computer Programmer, but I worked as a Systems Administrator for a number of years, so I might be able to help.
