Various Spawning Techniques???

I have been using families and arrays for spawning my 5 enemies in previous games. This would go as follows

every x seconds > create object > family.....

on created set speed etc

The problem is that when played on my android phone there is always slight lag from the enemies spawning.

I was suggested to use a InUse boolean for the enemies as it would cause less lag as it doesnt depend on the system??? I am a little confused to be honest. Are there any alternate spawning methods that wouldn't cause lag?

Creating a single instance shouldn't cause lag on most modern phones. Either your phone is just slow or there's something else going on. Could you post a capx of your issue?
