Has anyone noticed that even after enabling T2 Unlimited it takes a few minutes for the application to become responsive again? I have an application with a Spiky load. I have turned on T2 unlimited for this server. But still, I noticed that the application was becoming unresponsive for a few minutes when there was a continuous load. Didn't get a chance to get to the bottom of this yet. Did anybody else notice something similar?
