[rabbitmq-discuss] Per-Connection Flow Control - RMQ 2.8.1

Fri Mar 23 20:03:14 GMT 2012

Hi All,

Wondering is anyone having issues with the Per-Connection Flow Control 
in 2.8.1?
Under 2.7.1 was able to push about 4.5MB/s per connection (about 
~7000msg/s).
Under 2.8.1 I am hitting the flow control constantly at about 2.4MB/s 
per connection.
Clean installed 2.8.1 on the same hardware as 2.7.1.

Is there someway to configure/monitor what is causing the Flow Control 
to be tripped?

Thanks in Advance.
