Subject [jira] [Commented] (QPID-2410) perftest hang in SSL on Windows with large buffers
Date Sat, 02 Apr 2016 15:51:25 GMT

    [ https://issues.apache.org/jira/browse/QPID-2410?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15222921#comment-15222921

Rob Godfrey commented on QPID-2410:
-----------------------------------

Hi Tobias - changing the FRAME_MAX in ServerDelegate will certainly ensure that no frame over
16K, or whatever limit you need, will be allowed by the Java Broker.  If you are only using
the broker with the (broken) C++ client and SSL then that should be fine for you.  Obviously
other clients are capable of coping with properly sized frames and this may cause a bit of
a performance issue for them.  If the client provides enough information in its connection
properties to identify it as the C++ client running on Windows, then it would theoretically
be possible to conditionally return either 16K (for the broken client) or 64K for everything
else.

>         Environment: Windows client, Linux broker

> The following command:
>   perftest --count 1 --size 102400 -P ssl --port 5671 --broker linuxhost --username testuser
--password secret --mechanism PLAIN
> hangs on a Windows client.  Reducing the message body size to 1024 bytes makes the hang
go away, as does turning off SSL.
