This feature is badass. 

Load times between matches are easily 5x faster. 

All PS3 games should have the option (a la the NXE dashboard feature). 

Like some other users here noted, if everyone installs the game to the disc (360 and PS3) it could prevent some lag..  not 100% positive on that but hey, why not?  It makes sense to me.. and it certainly can't hurt..

Props to Capcom for making this in-game feature... something that Sony should have handled a long time ago.

Yeah I've just done this and load time increase is very noticeable, worth doing.

I did it straight away to prevent lag, it's the only way I've experienced the game.

A buttload of PS3 games have install; what makes this one different is the option to; usually its just you have to install or none at all. Not sure if it prevents lag, since its still pretty laggy after i installed.

I installed right away, but I still get a fair amount more lag online than I would like and some bad input delay. It does make matches load a whole lot faster though.

I didn't know of this. Awesome feature.

Yeah i did the install first thing as well

I'm running out of room on my HDD though lol
I guess I'll start deleting the installs of old games...

I havent done it as yet, but if its gonna increase loading times i guess its worth it.
