* Do not put a box around your map to fight leaks. Seal each section seperately and fight the leak war.
* Try to line up the faces of brushes with the same texture at the same scale. Then the engine may make them into one face plane.
* Avoid detail brushes, use texture to "fake it" instead.
* Plain make fewer brushes. Keep construction simple. HL and complexity mix poorly.
* There are some newer compiler programs being tested that remove unused and unneeded planes from the outside of a level. You could try to get and use one of them.
