Does it matter? This is just one of those required things. IMHO, most companies know there will be impact, and I would think they would accept any informational measurement after the fact. There are probably only a few cases where timing is so limited to where a skew would matter. Just

That cpu  is X5690. That is Westmere class.   We have a number of those doing 'meatball'  application loads that don't need the latest greatest cpu. I do not yet believe the Microcode fix for Westmere is out yet and it may never be. Intel has, so far, promised fixes for Haswell or better

[ovirt-users] Has meltdown impacted glusterFS performance?

I've been considering hyperconverged oVirt setup VS san/nas but I wonder how the meltdown patches have affected glusterFS performance since it is CPU intensive. Has anyone who has applied recent kernel updates noticed a performance drop with glusterFS?
