Sophie Blee-Goldman updated KAFKA-8802:
---------------------------------------
Description: The use of ConcurrentSkipListMap in the cache and in-memory
stores caused a performance regression in 2.3.0. We should revert back to using
TreeMap (was: A significant performance regression was seen between 2.2 and
2.3. For in-memory stores, about half of it was improved by removing the
ConcurrentSkipListMap. )
