Simple game lags while in editor but runs fine when build

I'm making a simple 2d game, a roguelike, turn based, so far there isn't much going on, only a player object, a random dungeon generator (that builds a small and simples 8x8tile room), and some enemies that work with a very basic random walk AI The game was lagging alot when I tested it in the editor, and the profiler showed some problems with Instantiate.Awake, GFX.WaitForPresent and EarlyUpdate, even after a google seached and some settings changed, the game kept laggin in the editor so I build it to see if the problem would continue, but it worked fine, no lags, it ran smoothly Anybody can help me? please
