The previous comments raise a question about how KiXtart tokenizes and runs scripts. IIRC, the script is initially parsed and tokenized to memory, then run from there. Granted, a ton of comments might slow down the this phase slightly, but should make no difference in the script execution speed once complete.

Personally I'd rather wait a few milliseconds more to load well-documented code than to spend much more time unraveling poorly-documented code (even my own) before making a change.
