Ben Manes commented on CASSANDRA-11452:
---------------------------------------
I assumed that it would be acceptable to reduce the penalty when a clash was
detected. The current version ejects the victim so that the candidates flow
through the probation space. I think that should be similar to your >=
approach, without reducing the hit rate in the small traces. Can you review the

> Following up from CASSANDRA-5863, to make best use of caching and to avoid
