[rabbitmq-discuss] Simple client/server running on different OS are lagging

[Matthew Sackman]

Hi Frank,

Not really too sure what to suggest, but others on the list have
reported better throughput when increasing buffers in Rabbit:

The easiest way to set these is to edit rabbitmq-server(.bat) directly -
these values are set near the top of rabbitmq-server and near the bottom
of rabbitmq-server.bat.

That may or may not solve these issues, but it's certainly worth trying.

If that's all one message, then the message must be fully received by
the broker before it starts being streamed out to the client.
