ISTM that improving interactive performance would also improve multiuser
performance in a server, as low latency and kernel preemption can increase
multiuser server responsiveness.

The stock gcc on 7.2.93 is still the RedHat-branded 2.96, but with lots of
fixes backported from higher versions.
However, the improved VM may indeed be a large part of it. It sure feels
faster.

Did you happen to report it to Red Hat's Skipjack list, or to
bugzilla.redhat.com/bugzilla? Helps make a better dist!
I have had less problems thus far with 7.2.93 than I ever did with 7.2.
