Lag reduction

[Obelisk]

Can anyone give me some ways to reduce lag on my map, i don't understand why it has so many lag spikes.

1) Keep the units on the screen to a minimum (don't mass units).
2) Don't use too many high polygon models.
3) Get rid of memory leaks.

Could you explain me when 3) happens?

Memory leaks occur sometimes when having faulty triggers and is usually because of a lack of variables. I think there is a tool out (I think somewhere on wc3campaigns.net) that can fix those problems. People who deal with JASS scripting can tell you more about that. Someone correct me if I'm wrong.
