fault tolerant heap

I installed corona 1.3 in a new workstation with 2 processors xeon e52630v3 and I get this error.
I read how to fix it but I wanted to ask is do you really need or only in cases where the machine is slow ?
I’m afraid to make the workstation unstable

This usually makes at least some parts of the rendering extremely slow (like 10x slower than they should be). Excluding the affected processes should not be unsafe in any way.
