Frozen props Server FPS drop

Hey got a problem with my Server…
everytime when props being welded (weld, smart constraint, stacker etc.) and frozen the Server fps drop to 5-10 fps while touching these props

can i freeze constraints too?
how can i prevent from lagging?

Here is an example:

Cant build elevators or huge bases anymore w/o lag…

(Im using ACF, wiremod, PewPew and Dupe 1 / 2… and some Building tools)

Well, that’s the physics causing the lag.
You might want to get a better computer?
There is not really anything you can do about it.

This problem appears only on my Linux gameserver…
on windows it works without lag
