Hi all,
I've recently run some tests to try and see how much overhead
clustering
brings. In short - I saw roughly a 50% reduction in message
throughput
when clients ran against a 2 node cluster vs a standalone broker.
I get about a 25% reduction running against a 4 node cluster.
Try --worker-threads=4.
<snip>
Just a quick follow-up - setting worker-threads=4 noticeably improved
throughput on a single queue in both the standalone and clustered
scenarios. It reduced total throughput somewhat when loading 8 queues
simultaneously (which you'd expect). The ratio of standalone:clustered
throughput remained at about 2:1. Will let know if we get any further
interesting results.
Cheers,
Andrew
