Comment (by Zerowalker):

 The only comparison i have done is on Playback, looking at CPU Usage etc.

 And i also have a file that's barely playable, with Lagarith Decoder i
 think it's playable but it may drop frames, not truly sure.

 But on LAV Filter, it's so slow on some parts that i would call it

 That's where i noticed that there was a huge difference, but i have no
 numbers on it.

 (The slow parts are Noisy stuff at 1920x1080p, so is probably quite
 possible to make a testbench with just much noise going on).
