Jitter optimization?

[McCarty]

Anyone know how to reduce equipment jitter (not network jitter)?

Mine is green for a bit, and then dips into yellow and red occasionally. Otherwise my setup seems to be good. Any recommendations? I tried the youtube guy method with the minimum processor thing at 100%, still issues. Using a MOTU Ultralite Mk2 its a bit old so maybe the culprit. Also vocals guitar and keyboard each with a plugin on it.

Any help appreciated!
