Hello, We are going to use riak in our project as a data storage. I set up following testing configuration:
One hardware server — 2*quad-core Xeon E5620, 2.40 GHz, 48Gb RAM, RAID1 (linux softraid, 2 sata disks). Installed OpenVZ kernel and set up 3 VE. Configured 3 riak instances (1 instance inside each VE) and joined each other to a ring. Then I put 2000 objects (average size 2kB) into riak. And started a stress test: about 10*100 requests (via REST) simultaneously to random-selected objects within 30 seconds. Request has been made to the one riak instance. Used multi-mechanize (http://code.google.com/p/multi-mechanize/) to make the stress-test. Got average response time about 1 second. It's too slow. I made second test — shutted down 2 instances, started the same test and god the same results. Can you help me to improve the perfomance? You can download stress-test results here: http://files.z9.ru/results_2010.11.30_18.05.06.zip _______________________________________________ riak-users mailing list riak-users@lists.basho.com http://lists.basho.com/mailman/listinfo/riak-users_lists.basho.com
