Sam Tunnicliffe commented on CASSANDRA-16360: --------------------------------------------- bq. Have you had chance to check the benchmark results? I'm afraid I haven't yet, but it is definitely still on my radar and hopefully I will get time to do it this week. > CRC32 is inefficient on x86 > --------------------------- > > Key: CASSANDRA-16360 > URL: https://issues.apache.org/jira/browse/CASSANDRA-16360 > Project: Cassandra > Issue Type: Improvement > Components: Messaging/Client > Reporter: Avi Kivity > Assignee: Alexey Zotov > Priority: Normal > Labels: protocolv5 > Fix For: 4.0.x > > > The client/server protocol specifies CRC24 and CRC32 as the checksum > algorithm (cql_protocol_V5_framing.asc). Those however are expensive to > compute; this affects both the client and the server. > > A better checksum algorithm is CRC32C, which has hardware support on x86 (as > well as other modern architectures). -- This message was sent by Atlassian Jira (v8.3.4#803005) --------------------------------------------------------------------- To unsubscribe, e-mail: commits-unsubscr...@cassandra.apache.org For additional commands, e-mail: commits-h...@cassandra.apache.org
