==== 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
}}}

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>)

10 loops, best of 3: 808 ms per loop

get status of all tasks of #123456

launchpadlib

 >>> b = launchpad.bugs[123456] 
 >>> print [t.status for t in b.bug_tasks] 

10 loops, best of 3: 2.23 s per loop
25 loops, best of 3: 2.28 s per loop

10 loops, best of 3: 2.86 s per loop
25 loops, best of 3: 2.69 s per loop

py-lp-bugs (text)

 >>> b = Bug(123456) 
 >>> print [t.status for t in b.infotable] 

10 loops, best of 3: 641 ms per loop
25 loops, best of 3: 639 ms per loop

10 loops, best of 3: 756 ms per loop
25 loops, best of 3: 751 ms per loop

change status of first task of #255634

py-lp-bugs (html)

 >>> status_map = {"New": "Invalid", "Invalid": "New"} 
 >>> b = Bug(255634) 
 >>> task = b.infotable[0] 
 >>> task.status = status_map[task.status] 
 >>> b.commit() 


10 loops, best of 3: 6.83 s per loop
25 loops, best of 3: 6.33 s per loop

launchpadlib

 >>> status_map = {"New": "Invalid", "Invalid": "New"} 
 >>> 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
