Hey, this is very little information to go with. I don't know if you've hosted any servers before so I'll just list some obvious things.
It might be just because your server is running 64 tickrate and you're comparing it to 100+ tick servers, which are more beginner friendly.
If you don't know what tickrate your server is, you can see it with net_graph -1 or 3 when connected.
You should also check your sv accelerate/airaccelerate/sv maxvelocity settings etc.
What do you mean 'probably because of the golden knife' ?
I'm aware that some maps have these items that give you weird physics, but you can remove them with
sourcemod stripper.
