Theoretically, rather than doing a full pn_messenger_stop + pn_messenger_start, you should be able to just do a pn_link_detach(link); /* modify the filter */ ; pn_link_open(link); and that might give you *slightly* better performance. But I think if you are going to be doing this on a per-message basis then you would be better of receiving all messages on the Link and just accepting those that you are interested in via correl id -- View this message in context: http://qpid.2158936.n2.nabble.com/CorrelationId-tp7614606p7617293.html Sent from the Apache Qpid Proton mailing list archive at Nabble.com.
