C. Scott Andreas updated CASSANDRA-7907: ---------------------------------------- Component/s: CQL > Determine how many network threads we need for native transport > --------------------------------------------------------------- > > Key: CASSANDRA-7907 > URL: https://issues.apache.org/jira/browse/CASSANDRA-7907 > Project: Cassandra > Issue Type: Improvement > Components: CQL > Reporter: Benedict > Priority: Minor > > With the introduction of CASSANDRA-4718, it is highly likely we can cope with > just _one_ network IO thread. We could even try pinning it to a single > (optionally configurable) core, and (also optionally) pin all other threads > to a different core, so that we can guarantee extremely prompt execution (and > if pinned to the correct core the OS uses for managing the network, improve > throughput further). > Testing this out will be challenging, as we need to simulate clients from > lots of IPs. However, it is quite likely this would reduce the percentage of > time spent in kernel networking calls, and the amount of context switching. -- This message was sent by Atlassian JIRA (v7.6.3#76005) --------------------------------------------------------------------- To unsubscribe, e-mail: commits-unsubscr...@cassandra.apache.org For additional commands, e-mail: commits-h...@cassandra.apache.org
