Yes, we have have jumbo frames on. Kernel and systems are in a good state. I've got the settings from the Linux perf tuning guide on the riak docs. Testing with iperf(1) shows our nodes can saturate the 10G interfaces without breaking a sweat - as long as the packets are large enough... 1) http:/

Chris, I've spoken to our performance-tuning experts and unfortunately they say there's not too much we can do with 1.4 to eek out more bandwidth for handoff. However, the two settings you might try: {riak_core, [ {handoff_batch_threshold, 1048576}, {handoff_concurrency, 2} ]} handoff_ba

Hi, Within the last few days I've started trying riak, with the intent of using it within a PoC. To that end, as I get started I've encountered some situations where I'd appreciate insight/feedback. 1. When developing is more than 1 node required? I built and started one node, but when I tried to

1. I use a one node deployment all the time for development. I jut tune the n val to 1. 3. Store whatever data you like. (Riak is being used in healthcare to store med data.) Unless it's transactional. Aka. +50$ to A from B, -50$ from B to A. I would not use riak for that. Cheers, Alexander
