Public bug reported:
I was wondering today why the timings for inserting events when running
our testsuite (or my benchmark scripts) are looking much better than the
timings in a 'real' daemon instance.
Some Data:
* inserting 500 events at once in my benchmarks: ~0.09 sec
* inserting the same 500 events at once in a 'real' zeitgeist session: ~0.185
sec
You can reproduce this tests by running the attached script like
ZEITGEIST_DEFAULT_EXTENSIONS="_zeitgeist.engine.extensions.datasource_registry.DataSourceRegistry"
PYTHONPATH=. python /tmp/test_insert_events.py
PYTHONPATH=. python /tmp/test_insert_events.py
and compare outputs.
To simulate the scenario of multiple running instances of the same
application, uncomment the lines 26+ in the script, you will get even
worse results.
