Server FPS low with few players
I'm running a rust server on a VDS with 8 cores (3.2ghz each), 16 gigs of ddr4 ram, 1gbps internet, 300gb ssd - but my server fps is waving between 20-100 - I'd say it averages to 50 - with only a few players connected!

I have vanish, spectate, removaltool and adminradar plugins activated in my oxide - but the problem remains.

Is there anything specific I have to keep in mind? I don't think this fps is normal, as, when I host a server on my home gaming rig fps is 240 stable.
What is your map size, serverinfo response, plugins
I had the same problem like you, i did o.plugins, i saw what plugins are rrequirinh to many time (00.0s), i removed the config and make it again 100% focus, now is fine, hope you figure it out, my problem was copying and paste other configs from websites example: infopanel

Post the o.plugins result
What is your mapsize?
What is your entity count?
How many times do you wipe?
