I don't mean a specific console. Is Japanese faster in general on all consoles, just one or not at all?

Morse found out a while ago, that the japanese Gamecube version is actually a bit slower than the PAL version. Jap version also has the weird Ashley camera angles, which makes it harder/slower to navigate. If you have the choice, get a PAL version for whatever console you run.

Ok thanks. Just wondering since most of the Resident Evil games are faster in Japanese

For RE4 the region only makes a difference on Gamecube. You should Play PAL as it's the fastest one.
