The reason for lag is usually due to your processor having to work hard on loading everything and visualizing the particles, this is pretty much your computers issue, not the map. But it's possible that I'm wrong.

it's strange then

You can always try multicore rendering. Most of the time the lag is if you are on one corner of the map and try to look directly to the opposite corner. I have no easy way to optimize the map without making it look like crap. Engine limitations.
