Methode so Maps have less delay

“I’ve heard that there’s a method to reduce delay in maps, even when they have a lot of content. For example, I’ve seen maps with 20 songs, plenty of features, and 27,000 memory that have less delay than my map, which only uses 14,000 memory. My map doesn’t have anything particularly complex—just weapons, a performance button, and buttons for 185 HP and 200 HB.

My question is: what is this method to reduce delay, and how can I apply it to my map?”
