Maxim Muzafarov commented on CASSANDRA-16360: --------------------------------------------- [~jjordan] Thanks for your interest in this matter. I have prepared the poc to test some options that we might have. I need to prepare one more benchmark and will be back here with the report and options that work for us. The raw results are here: https://gist.github.com/Mmuzaf/349c5f8dbdfada82e5199f36cbfc15b4 > 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: Maxim Muzafarov > Priority: Normal > Labels: protocolv6 > Fix For: 5.x > > Time Spent: 10m > Remaining Estimate: 0h > > 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 (v8.20.10#820010) --------------------------------------------------------------------- To unsubscribe, e-mail: commits-unsubscr...@cassandra.apache.org For additional commands, e-mail: commits-h...@cassandra.apache.org
