It'll be a 1-2-3 punch. 1 being a blip, 2 also being a blip, then 3 will be 4 seconds or more.= of lag.
Are you sure everybody on the server is experiencing this?
It's clearly not CPU-related.
This is nothing like what I am experiencing. Does this 1-2-3 pattern keep happening routinely, at the same intervals?
I only get about 0.3 seconds of lag, every 25 seconds. And it has mostly stopped now.
