My map randomly lags everyone in the game to the point where everyone leaves and can't stand it anymore. I see nothing that would cause this massive lag, but nontheless it happens everygame except 1 no matter whos in the game. It happens in different places every game and 1 game it didnt happen at all...

Well, if you let us see the map that might help...
Well, I don't want it to be stolen, so I'll post a Protected version.
Does it still lag when you're only player in the game? If it doesn't, you have connection problems or the other players do. If it still lags, it's time to buy a better computer.

No, It lags no matter whos in there, I even left when it started lagging once yet they said there was no change in lag.
Yes, but does it lag when YOU are the ONLY person there?

I tried the map in single player...and suprisingly it did lag. I'm pretty sure it's not my computer because I have an AMD Athlon XP 2600+ CPU with 1 GB of DDR RAM. Could it be the massive terrain picture "Ruff Riders"?
Well I havn't played the map very much, but a few "rounds", single player, not online, but easy enough, it just seems like you have too many triggers. This might sound dumb, and not possible, but I think if you have too many triggers, they DO indeed begin to lag. Played many RPG's like this (mainly dealing with "waits", not with over-trigger use). I wish I could LOOK at your map and see what exactly you did.
Great ideas for bounds though.
On the FIRST "round" it seems they are transmissions, and a million transmissions a second most definately will lag a computer, notice the flickering Portrait?
The second round moves fairly smoothly.
Just take note of each round and find out what's running too fast and how much information each trigger is putting out. Like the transmissions, sending out that many is a whole lot of information being read at once, taking note of display message, sound, portrait, location of unit, highlight unit (even if no sound is used, etc).
If you want me to take a look at the triggers, switch them around, then resend it to you, with what I changed, PM the unprotected file to me. If not, play around with it yourself and test out some theories.
Good Luck!!!
Check conflicting wait or transmission triggers. As in, make sure they aren't going off at the same time becuase they will add up then lag the game.
Are you cycleing a location between burrowed units? Or creating any units for that purpose? I doubt its the transmissions because the next level seemed the same to me. But it is likely a unit being removed and created constantly or something along that nature. (how many lurkers are on the second level?)
Well, There are 100 lurkers in the second level.
As for the transmission level, I'm creating the units, then im removing them after transmissions finish, I do this so transmission doesnt repeat and look weird. I have no idea why this could or would cause lag. Besides I didn't have the problem with lag until recently, so its not levels 2-5.
