Btw. This hotfix did nothing.
I'd go as far as saying, it made it worse.

I’ve done a vehicle wipe 2 days after 1.10 release, had about 40 vehicles, and I saw no difference in server FPS. After combing through 1.10, learning everything it’s introduced, I feel this is just the side affect of its new features. hopefully in future updates they can optimize these new features, because this is a very negative side affect we are experiencing.

Well after about week of 1.10
I'll average about 25-30 players and see a constant average 1.5k-2k FPS with that many players.
I've ran modded servers since 1.06, and I will say I'm use to being able to push 3k-3.5k with that many players. I would say I'm very experienced when it comes to running servers.
When I ran ApocalypticSixx ( 1.06-1.09 ), I did 70 slot servers, and ran 2 instances on each machine I had. I had 4 servers total, 2 machines.
I would average 500-1k FPS with 70 players on each instance. So 140 players on 1 machine.
