The issues > seems to be related on sends to the NewMessage() call. For receives, the > bottleneck is both NewMessage() and the call to actually receive the message. > > > This behavior is not unexpected as CGO is a well-known bottleneck. Would it > be possible to have a NewMessage() call that return multiple messages and a > recv call that took an "At most" argument. i.e. recv(10) would receive 10 or > fewer messages that might be waiting in the queue. Also, it would be nice to > be able to trade latency for throughput in that the callback wasn't triggered > until N messages were recieved (with timeout).... -- This message was sent by Atlassian JIRA (v7.6.3#76005) --------------------------------------------------------------------- To unsubscribe, e-mail: dev-unsubscr...@qpid.apache.org For additional commands, e-mail: dev-h...@qpid.apache.org
