Benoit Tellier commented on JAMES-3191: --------------------------------------- https://github.com/linagora/james-project/pull/3408 solved the performance issue du to a rabbitmq overuse due to an infinite processing loop. https://github.com/linagora/james-project/pull/3390 contributed reactive registration to the event bus > Key registration is slow > ------------------------ > > Key: JAMES-3191 > URL: https://issues.apache.org/jira/browse/JAMES-3191 > Project: James Server > Issue Type: Improvement > Components: eventbus, IMAPServer > Affects Versions: master > Reporter: Benoit Tellier > Priority: Major > Labels: perf > > We noticed that on *master* SELECT IMAP command is significatively slow > (several minutes) on top of the distributed profile. (See attached > instrumentation average time and percentiles) > A quick performance review links this to listener registration (by key). > A code review leads to: > - The low channel number (3) maybe this count can be safely raised to a > higher number? Like 10? Maybe even configurable? > - EventBus::Register operation is handling IO but is synchronous. The > reactor scheduler backing it up is unspecifed (thus is likely the parrallel > one). We should let the caller specify the scheduler he whishes to run. -- This message was sent by Atlassian Jira (v8.3.4#803005) --------------------------------------------------------------------- To unsubscribe, e-mail: server-dev-unsubscr...@james.apache.org For additional commands, e-mail: server-dev-h...@james.apache.org
