Compare_lplib_pylpbugs

time based comparison of python-launchpad-bugs and launchpadlib

This is still work in progress. python's timeit is used.

Preparation

launchpadlib

There are two files with credentials for STAGING and EDGE, for each mode the connector is created by 

>>> credentials = Credentials()
>>> credentials.load(open(<file>))
>>> launchpad = Launchpad(credentials, <SERVER-const>)

python-launchpad-bugs (text)

(read-only access) 

>>> Bug = ConnectBug("text")
>>> Bug.set_connection_mode(<SERVER-const>)

python-launchpad-bugs (html)

(this connection mode is used for write-access) 

>>> Bug = ConnectBug("html")
>>> Bug.authentication = <cookie-file>
>>> Bug.set_connection_mode(<SERVER-const>)

 >>> b = launchpad.bugs[255634] 
 >>> task = list(b.bug_tasks)[0] 
 >>> task.transitionToStatus(status=status_map[task.status]) 


10 loops, best of 3: 3.66 s per loop
25 loops, best of 3: 4.51 s per loop

Conclusion

  • for read-only access python-launchpad-bugs in the text mode is about three times faster than launchpadlib

  • write-access with launchpadlib is two times faster than python-launchpad-bugs in the html mode

Conclusion

  • I'm not able to get time-stable results from staging, will try it later again

Preparations

The timings for launchpadlib are now part of the launchpad profile for ipython. To run this timings get the code from lp:~thekorn/+junk/ipython.launchpad.profile, copy the profile to ~/.ipython and run: 

% LPTIMING=1 ipython -p launchpad  #for staging, or
% LPMODE=edge LPTIMING=1 ipython -p launchpad  #for edge

Conclusion

  • edge is looking good, speed seems to be improved since I checked it the last time few month ago
