Andrew - are you calling send() from within a reactor callback? Or from another thread?
I'm not very familiar with the Java reactor, but the C reactor has a method called pn_reactor_wakeup() which causes it to immediately return from the blocking select() call. -K ----- Original Message ----- > From: "Andrew Buckley" <and...@microsoft.com> > To: d...@qpid.apache.org, proton@qpid.apache.org > Sent: Thursday, February 25, 2016 12:45:04 PM > Subject: RE: Proton-J Reactor sending delay > > Ah, thanks Robbie.
