-----------------------------------
Summary: Investigate changes to threading model for network
consumers to improve performance for small messages
Key: CASSANDRA-7045
URL: https://issues.apache.org/jira/browse/CASSANDRA-7045
Project: Cassandra
Issue Type: Improvement
Components: Core
Reporter: Benedict
Assignee: Benedict
See CASSANDRA-7029 for original discussion.
We can (maybe) optimise the threading model for network consumers: since we
generally process very small messages (200 bytes not at all implausible), the
thread signalling costs on the processing thread can actually dramatically
impede throughput. In general it costs ~10micros to signal (and passing the
message to another thread for processing in the current model requires
signalling). For 200-byte messages this caps our throughput at 20MB/s.
