[rabbitmq-discuss] Performance question

I have a one producer, one consumer queue running locally for a performance
test. In terms of just server and client configuration, what is the best way
to increase performance. For a simple queue publisher and consumer, I¹m
getting about 10k a second for simple byte messages.

Here is some of the code:

channel.exchangeDeclare("exchangename", "direct");
channel.queueDeclare("queuename");                    channel
.queueBind("queuename", "exchangename",
"routingKey");                     byte[] messageBodyBytes = new byte[0];
int count = 0;                    long start = System.currentTimeMillis();
String name = Thread.currentThread().getName();                    for (int
i = 0; i < 100000; i++) {
channel.basicPublish("exchangename", "routingKey",
null, messageBodyBytes);                        count++;
if ((System.currentTimeMillis() - start) > 1000) {
System.out.println(name + "-" + count);                            count =
0;                            start = System.currentTimeMillis();
}                     }

channel.basicConsume("queuename", false, new DefaultConsumer(channel) {
int count = 0;            long start = System.currentTimeMillis();
@Override            public void handleDelivery(String consumerTag, Envelope
envelope,                    BasicProperties properties, byte[] body) throws
IOException {                count++;                if
((System.currentTimeMillis() - start) > 1000) {
System.out.println(count);                    count = 0;
start = System.currentTimeMillis();                }
this.getChannel().basicAck(envelope.getDeliveryTag(), false);            }

Is there some way I can increase the performance? From the tests I have seen
online, I hear numbers of millions of messages a second.
