Determine which resource causes lag. OneSync

Hey

Is there any way to determine which resource causes lag on Linux server?
We have couple hitchs sometimes on 32/32 but server is running smooth. Only if We change to the OneSync and We have about 50-55 (and above), game is almost unplayable. We have Hitch net errors and standard hitches.

I know Windows have ETW Tracing which helps with determine leaking. Is there any Linux alternative?
Maybe you have any ideas how to find out this laggy resource?

We appreciate every help.

Sounds like also some clientside stuff lagging? for client side you can open the f8 console and type

Not sure about serverside on Linux
