Consider auto-tuning the per-connection buffers (receive_buffer_size and send_buffer_size)
------------------------------------------------------------------------------------------

                 Key: APLO-163
                 URL: https://issues.apache.org/jira/browse/APLO-163
             Project: ActiveMQ Apollo
          Issue Type: Improvement
            Reporter: Lionel Cons


As seen in APLO-160, the size of the per-connection buffers can greatly impact the memory
usage.

Since it can be difficult to predict how many concurrent connections will have to be handled
by the broker, it would be good if the broker could auto-tune the buffer sizes.

The broker should be able to get JVM memory information and decide how much space should be
devoted to connection buffers (as opposed to other memory usages). Then, based on the number
of existing connections and the total buffer space they occupy, the broker could tune the
per-connection buffer sizes of the new connections (at least, it could also adjust the existing
buffers).
