Francesco Nigro commented on ARTEMIS-1307: ------------------------------------------ I was young(er) and more naive and just wanted to make "everything" faster :) > Improve performance of OrderedExecutor > -------------------------------------- > > Key: ARTEMIS-1307 > URL: https://issues.apache.org/jira/browse/ARTEMIS-1307 > Project: ActiveMQ Artemis > Issue Type: Improvement > Components: Broker > Affects Versions: 2.2.0 > Reporter: Francesco Nigro > Assignee: Francesco Nigro > Priority: Minor > > The current ordered executor is using ConcurrentLinkedQueue that: > - has expensive queue::size operation (ie O( n )) > - has node instances scattered in the heap > There are faster and cheaper alternatives in specialized libraries (eg > JCtools) that could be used instead of it to be more friendly with the GC and > to provide more throughput too when CPU bound. -- This message was sent by Atlassian Jira (v8.20.10#820010)
