Are entities causing my horrible TPS? Pls send halp

Hi there, I have horrible TPS near constantly once we reach over 30 players. If I’m reading the timings right, it’s being caused by entities. Now, I’m pretty sure I’ve set all of my settings to be that of those in the Optimization Guide started by frash23, and I’m still running into constant issues. Any insight on what I can do to fix this would be most appreciated. <3
I disabled React about halfway through this first timings because I’ve always had serious doubts as to it’s helpfulness.
