Hi, I wondered if you managed to significantly improve your Riak CS performance, or not?
I just ask as we've been getting not-dissimilar performance out of Riak CS too (4-5 mbyte/sec max per client, on bare metal hardware), for quite a long time. (I swear it was faster originally, when there was a lot less data in the whole system.) This is after applying all the tweaks available -- networking stack, filesystem mount options, assorted Erlang vm.args, and increased put concurrency/buffer options. We put up with it because it's been just-about sufficient enough for our needs and Riak CS has been reliable and easy to administer -- but it's becoming more of an issue, and so I'm curious to know if other people *do* manage to achieve *good* per-client speeds out of Riak CS or if this is just how things always are? And we're way off the mark, maybe we can find out why.. Details of our setup: 6 node cluster. RIng size of 64. Riak 1.4.10 Riak CS 1.5.2 (installed from official Basho repos) Tests conducted using both multi-part and non-multi-part upload mode; performance is similar with both. Tested against cluster when very lightly loaded. For the sake of testing, a 100M file is being used, that contains random (hard to compress) data.
