Lior Golan commented on CASSANDRA-5862:
---------------------------------------
Are you computing the checksum on the data before or after compression? If you
are computing the checksum of the uncompressed data, then it might be useful to
switch to checksum the compressed data (less data to checksum)
> Switch to adler checksum for sstables

> it checksums each mutation individually.)
