AV Startup Times

ive been gone from these forums for a while so im trying to catch up again, anyways here's my question. Im looking for some hard proof, not loosely based opinion, but which AV's have the approximate fastest startup times and overall system responsiveness.

yes i know it varies between systems so this question wuld probly be easiest to answer by somebody who has tested multiple AV's on a single machine. ive been happy with Avira but my subscription is almost over so ill be looking for something new and i really need to find the speediest AV i can since even though avira is light, id like some lighter since i am quite an impatient person as well as a gamer. thanks for ur help to anyone who replies.

btw im looking for AV's not an internet security suite.
