Performance Impact on Disabling the Kernel PTI?
-
Hi,
I am using pfsense on a dedicated machine and it's working on a live system. If I disable the Meltdown workaround (kernel PTI), does the performance increase? Will it need reboot or is there a chance I may have stability problems on the system ?
Thanks for the commentsEnis K.

From my understanding you will have to reboot. As to performance increase, that is a prob sure but question is will you be able to notice it? if the system is struggling then its most likely undersized for what your wanting to do with it.

It's mostly less then %1 cpu load, but we are running on such an environment that any less latency is an important gain. So I am doing everything to increase the performance.
What is the performance gain when I disable it? %10?
and the risk that something may go wrong, such as not a successful reboot?
