High inter-dc latency could make writes more likely not to land, which
would make repair do more work.
Also true for read and writes - waiting for the cross-dc request will keep
threads around longer, so more concurrent work, so more GC.
May be that the GC is coming from the read/write path, and
Can inter dc latency cause high gc pauses? Other clusters working fine with
same configuration? Only this particular cluster is giving long GC pauses
during repair.

Dear community,
is someone working on this ticket? This is clearly performance regression
and we stuck with 3.11.6 and could not upgrade to latest version.
