Easy way to group units and stop lag?

Could anyone post how to stop the lag buildup for the create units trigger? Please?

The action its self creates minual lag if it not dones not create 1200 in a sec. Show me the trigger so i can help more cause right now i see no problem. More then likely its how you have used this action. That or you have a very old computer.

My computer is not very old I just want to eliminate lag from the groups and I heard there was a way to do it.

Trigger

Event- Every 60 seconds of game time

Action- Create 3 footman for player one red at location
- Create 2 archers for player one red at location
-Order every unit within Location to location2.

I want to make it so this wont lag as much, because I have 5 spawns coming out of each base.

Event- Every 60 seconds of game time

is what would cause lag if any but i can see any thing else i could be other triggers that are going off. Do you have alot of Timed events in you map cause is so thats your problem maps with more the 7 of these can case major lag.

Cooler, i have a question. Would it help if a unit spawn trigger like the one xzarol has given was changed to look like this instead?

Event-
None (run by another trigger)
Actions-
Create XYZ ### at blah blah
Create Blah ### at XYZ
Order blahXYZ to move to blah
Wait 60 seconds
Trigger- run this trigger

use polled wait and that would work. B ut dont ever set it to wait .01 or no wait at all beacuse that will cause end less loop and shut down wc3.

Err, excuse my ignorance, but what's a polled wait? Is it that "Wait for condition, checking every # seconds" action?

Its in ums editor next to wait it takes the time of every player and takes the avarge in b net game (stops lag).

Thanks for your help COOLer! It would NEVER have occured to me to use that instead.
