We have deployed a 4 node riak cluster on AWS with eLevelDB backend. We have been benchmarking it for last couple of days using basho-bench, with _unimpressive_ results. Attached "app.config" and "basho-bench.config".
Following are the only changes made to "vm.args" ## Enable kernel poll and a few async threads +K true +A 16 We did following two tests. Test 1 4 nodes m1.medium instances, XFS 50G EBS with RAID10 on Ubuntu 12.04 AMI 50 concurrent connections for 5 hours HTTP Raw Driver Only Inserts (since we are expecting very heavy writes) Click on the following link to view the performance graph generated through R. https://www.dropbox.com/s/2a64jvpf4w00487/Test1.png Test 2 4 nodes m1.medium instances, XFS with default ~340G Ephemeral on Ubuntu 12.04 AMI 50 concurrent connections for 5 hours HTTP Raw Driver Only Inserts (since we are expecting very heavy writes) Click on the following link to view the performance graph generated through R. https://www.dropbox.com/s/ou8j03gvd36xo9h/Test2.png -- With Regards Abhishek Amberkar
