Ben Manes commented on CASSANDRA-11452:
---------------------------------------
For large traces the difference is marginal, with s3 showing a 2% loss. For
small traces the difference can be substantial
db: 51.29 -> 51.52
s3: 51.10 -> 49.12
oltp: 37.91 -> 38.10
multi1: 55.59 -> 50.50
gli: 34.16 -> 16.11
cs: 30.31 -> 26.74

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