I ask because someone at VideoHelp was asking about slow encoding speed recently and avs4x264mod seemed like it might be the culprit.
The way I understand it MeGUI uses avs4x264mod when Avisynth is 32 bit and the x264 encoder is 64 bit. I don't know if there's a way to bypass it when running a 64 bit OS. I'm using XP myself so avs4x264mod is never used.
It is very unlikely for avs4x264mod to be a bottleneck. It simply pipes the video data to x264 to allow 32 bit avisynth input to 64 bit x264. No way to get around it if you want to use 64 bit x264 and 32 bit Avisynth, you could use 32 bit x264 on a 64 bit OS but it is quite a bit slower.

There are other options though, I use a newer version of avs2yuv so I am not sure how avs4x264mod works but maybe avs4x264mod doesn't call distributor() itself so it would need to be added to the end of a MT script.
