Mark Soderquist commented on QPID-6944:
---------------------------------------
I have applied the patch and it appears to have worked. The average CPU use has
dropped down to ~3% with spikes whenever messages are sent. I'll attach a
screen shot for reference.

> Qpid is experiencing high CPU use when a message is sent. While the
> application still functions it causes the CPU to run at nearly 100%. This has
> been narrowed down to enabling SSL on the AMQP port. With SSL disabled there
> is normal CPU use, but with it enable the CPU use spike when messages are
> received or consumed.
