Horrible TPS on my ATM8 server

Hey y'all! Posting here as i'm not quite proficient in reading Spark reports yet. I have a modded server i'm hosting and I can tell there's some abnormal stuff going on in the reporter. I'm just not sure "what" or "how". I'd really really appreciate if you guys could take a look.

Running ATM8, so it's a forge server
