Lag is hardware-related looks like. Present on CM10 based ROMs as well. On stock-based disabling S-Voice helps just a little bit when it comes to waking up from Home button...
Killing me as well. :\ What I getting used to is to press Home while pulling phone out - straight away so by the time I get it in position to work with, the screen is either already on or will be on in a 200-500 ms.
Still this is a most frustrating "feature" of SGS3 that will most likely force me to look for replacements once those are available on the market.
