Subject [jira] [Updated] (QPID-3297) Python SWIG client API seems no faster than pure Python client API
Date Wed, 08 Jun 2011 15:06:59 GMT

     [ https://issues.apache.org/jira/browse/QPID-3297?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Anthony Foglia updated QPID-3297:
---------------------------------

    Attachment: batch_producer.swig.out
                batch_producer.python.out
                timing_tests.py
                timing_consumer.messaging.py
                batch_producer.py

These are my test producer, test consumer, and test runner.  Also there are two timings results
from using the pure python API and the SWIG api.  (I suggest just looking at the tail of the
files for the summaries.)

0.7.946106-15, SWIG Python client version 0.10.

> I am trying to get as high a transfer rate as possible, and while the qpid-perftest 50,000
transfers/sec (34,000 publish, 26,000 subscribe), the Python consumer I wrote is only reading
~1600 on average.  I tried the swig version and the average speeds are roughly the same (if
not worse), but the variance is much greater.
> I'm opening this issue so I can share my client code with others since I can't put it
on the mailing list.  Here is the original thread: http://mail-archives.apache.org/mod_mbox/qpid-users/201106.mbox/ajax/%3C4DE921C0.2000509@princeton.com%3E
