Hello. Nobody answered my previous post (http://lists.basho.com/pipermail/riak-users_lists.basho.com/2010-December/002632.html). But I'll try again...
I made different stress-test. One hardware server — 2*quad-core Xeon E5620, 2.40 GHz, 48Gb RAM, RAID1 (linux softraid, 2 sata disks). Debian GNU/Linux squeeze Installed erlang R14. Compiled riak from sources. sys_system_version : <<"Erlang R14B (erts-5.8.1) [source] [64-bit] [smp:16:16] [rq:16] [async-threads:64] [kernel-poll:true]">> sys_system_architecture : <<"x86_64-pc-linux-gnu">> Configured 3 riak instances (no OpenVZ at this time) and joined each other into a ring. Then I put 50 objects (average size 2-18kB) into riak. And started a stress test: about 5*10 requests (via REST) simultaneously to random-selected objects within 300 seconds. Requests has been made to all 3 instances via load-balancing HTTP proxy (nginx). Used multi-mechanize (http://code.google.com/p/multi-mechanize/) to make the stress-test. Got pretty good perfomance and two very bad throughput slowdowns. You can see results here: http://files.z9.ru/results_2011.01.17_16.36.00/results.html Again: can you help me to eliminate that perfomance downfalls? _______________________________________________ riak-users mailing list riak-users@lists.basho.com http://lists.basho.com/mailman/listinfo/riak-users_lists.basho.com
