I have no way of testing it, but I can spin up a test server and send you the info if you want test with it.

I think the Xeon Platform has TPP support going farther back than Core or HEDT, however on older Xeon CPUs the performance penalty for running the mitigations was severe, in excess of 25%.

Even with that large a penalty, I doubt you'd see any performance loss, the Valheim server doesn't bury the performance needle, so to speak.
