Comment (by mascguy):
While I'm still working on generating profiler results, the following
timings illustrate the problem. These were run in a macOS 10.12 VM, though
the specific macOS release doesn't matter; they're consistent across
versions.
||=Operation =||=Time: 2.6.4 =||=Time: 2.7.1 =||
||port reclaim|| 25.4 secs|| 50.2 secs||
||port clean --all installed|| 28.7 secs|| 54.1 secs||
Interestingly enough, the processing time is nearly doubled for 2.7.x, vs.
2.6.4.
Is it possible we inadvertently made a change, which results in the
various logic running twice for each operation?
