Michael Kjellman commented on CASSANDRA-14002:
----------------------------------------------
So +1 from me. Comments look good and I don't even see any code style related
nits. 50% faster is a bigger win than I expected when I saw it in profiling a
long long long time ago to be honest... so that's super awesome news!
Looks like a few repair related dtests did fail but looking at stdout it seems
that this is weirdness with the Apache Jenkins instance and ccm not starting
instances cleanly and not any fallout from this change.
