Re: [Rdo-list] python-kombu 1.1.3 is not recommended version of Icehouse

Hi, Thank you for good suggestions. There is benchmark tool for oslo.messaging introduced at last Atlanta summit. Etherpad: https://etherpad.openstack.org/p/juno-oslo.messaging-amqp-1.0 Code: https://github.com/grs/ombt When I tried this benchmarking tool on my RDO box (kombu 1.1.3-2), I got a poor throughtput (7.7 request/sec). But just updating kombu to 2.5.8, I got a better throughput (91 reuest/sec). I don't know why kombu 1.1.3-2 results such a poor performance. thanks, Koji ---- ### kombu 1.1.3-2 $ ./ombt.py --calls 100 --conf rpc_backend rabbit --conf rabbit_host 192.168.101.33 --conf rabbit_password guest INFO:oslo.messaging._drivers.impl_rabbit:Connected to AMQP server on 192.168.101.33:5672 INFO:oslo.messaging._drivers.impl_rabbit:Connected to AMQP server on 192.168.101.33:5672 INFO:oslo.messaging._drivers.impl_rabbit:Connected to AMQP server on 192.168.101.33:5672 INFO:oslo.messaging._drivers.impl_rabbit:Connected to AMQP server on 192.168.101.33:5672 Call 10 of 100 completed Call 20 of 100 completed Call 30 of 100 completed Call 40 of 100 completed Call 50 of 100 completed Call 60 of 100 completed Call 70 of 100 completed Call 80 of 100 completed Call 90 of 100 completed Call 100 of 100 completed {'latency': {'count': 100, 'min': 123.36111068725586, 'max': 258.3320140838623, 'average': 129.59874868392944, '_sum_of_squares': 1699774.5017536662, 'std_deviation': 14.209481239522995, 'total': 12959.874868392944}, 'throughput': 7.7150386788072778, 'calls': 100} ---- ---- ### kombu-2.5.8-1.el6 $ ./ombt.py --calls 100 --conf rpc_backend rabbit --conf rabbit_host 192.168.101.33 --conf rabbit_password guest INFO:oslo.messaging._drivers.impl_rabbit:Connected to AMQP server on 192.168.101.33:5672 INFO:oslo.messaging._drivers.impl_rabbit:Connected to AMQP server on 192.168.101.33:5672 /usr/lib/python2.6/site-packages/amqp/channel.py:608: DeprecationWarning: auto_delete exchanges has been deprecated 'auto_delete exchanges has been deprecated')) INFO:oslo.messaging._drivers.impl_rabbit:Connected to AMQP server on 192.168.101.33:5672 INFO:oslo.messaging._drivers.impl_rabbit:Connected to AMQP server on 192.168.101.33:5672 Call 10 of 100 completed Call 20 of 100 completed Call 30 of 100 completed Call 40 of 100 completed Call 50 of 100 completed Call 60 of 100 completed Call 70 of 100 completed Call 80 of 100 completed Call 90 of 100 completed Call 100 of 100 completed {'latency': {'count': 100, 'min': 6.4032077789306641, 'max': 111.25898361206055, 'average': 10.875468254089355, '_sum_of_squares': 22480.778639419441, 'std_deviation': 10.321432877681714, 'total': 1087.5468254089355}, 'throughput': 91.755911089409807, 'calls': 100} ---- (2014/05/22 22:27), Pádraig Brady wrote:
