What Avisynth MT mode do I use for 8-core PC?

[VideoFanatic]

As the title. I did this was a dual core.

setmtmode(5,3)
Mpeg2Source("J:\2 = New\Raw August 06 2001.d2v", CPU=6)
setmtmode(2,0)

Is there a page which explains the usage? I looked here but I didn't understand it: http://avisynth.org/mediawiki/MT_support_page#MT_usage

Use the lowest mode you can. But many filters don't work with the lower modes so you have to use higher modes. Mpeg2Source() requires mode 5. After calling it you can whatever mode works for your other filters. Experiment with the number of threads to find the fastest for the particular filter combination. Usually 1x to 2x the number of cores.
