Yes.

I'll suggest that before you do any serious perf measurement or try to
"squeeze more performance out of" *any* codebase you update to a current
release and not measure a two year / four version old release.

There are people for whom tracking performance of a set up over time is
important and for them measuring obsolete versions is useful. However, if
you have a target and are trying to figure out whether a setup can _reach_
that target then measuring an older release tells you nothing, because you
would never deploy an out of date release. I Would Dearly Hope.
