A Map with ONE trigger lags? Say what?

My map lags. A lot. Not on my end, but on the end of thepeople playing with me. The internet speed in my house also goes to hell. The weird thing is, I only have ONE trigger, and it does not create special effects, buffs...all it does is remove units when theyre finished training and replace with a random creep equal to their level.

One thing I did do was, to get more creeps, go to the editor-tileset value under each and every creep and set it to "all". Could this cause lag, even though I'm only using the default Icecrown Glacier tileset?

Again, I have ZERO special effects going on, no music, no custom buffs or anything, normal amounts of units...

I PREVIOUSLY had about 45 minutes worth of imported music, but I have removed that. That used to cause ungodly long saving times.

Post the map or the trigger. Also large maps with a lot of creeps require more computer resources and may slow the game down, and there is also first time load lag. Anyways, post the trigger or upload the map itself.

I looked at the triggers and played the map, and I didn't notice any lag. Does the game lag right away or later on into the game? I think I found a trigger which leaks and would cause problems later on in the game. "GetUnitLoc" creates a location which is not removed. Set "GetUnitLoc" to a variable first then remove when done with it. I've uploaded a map with the fix. Give it a try and see if it helps.

Definitely not the creep thing, I use that in a whole heap of my maps.
I sure hope you didn't use the object editor and do every every creep manually.

As I spent twenty minutes doing exactly that, I was constantly thinking "There has to be a better way, but I bet by the time I figure it out I could have been done by then."
I feel really stupid.

The lag was periodic "waiting for host..." by the person I was playing with. It might be unrelated to the map, but thanks for the memory leak fix.
