I'm trying to find out when the new persister will be available. I've seen mention that it was to be ready by July of last year (<a href="http://lists.rabbitmq.com/pipermail/rabbitmq-discuss/2009-June/003667.html">http://lists.rabbitmq.com/pipermail/rabbitmq-discuss/2009-June/003667.html</a>), and further mention in November of it not being ready yet (<a href="http://lists.rabbitmq.com/pipermail/rabbitmq-discuss/2009-November/005386.html">http://lists.rabbitmq.com/pipermail/rabbitmq-discuss/2009-November/005386.html</a>).<div>
<br></div><div>The reason I ask is that we are attempting to publish ~1000 msgs/sec on a single rabbit node, in a persisted queue. The queue is then read by a java app on a geographically distant server over the internet, using basic.consume. We also require transactional consumption, so currently wrap a batch of X (500 for example) messages in a transaction, acking the last one (passing true to ack multiple). We have qos set to batch size * 2 (1000 in the above example).</div>
<div><br></div><div>We're only managing to get something like 50 or so msgs/sec at the moment. The consumption of the messages is slow, but the tx.commit varies in speed from a second to many (sometimes even as long as a minute).</div>
<div><br></div><div>The version of rabbitmq we currently have installed is 1.7.0. We are planning to test with 1.7.2 later today to see if this helps any.</div><div><br></div><div>What are we doing wrong?</div><div><br></div>
