As part of the performance testing story, spent some time and added more
info to our existing Performance Testing document. I did a further break
down on areas we might want to look into per component. I also added few
tools that i have used before or ran into that could be useful. This is
just a start and looking for some discussion to go around it.

Please feel to add or update any further areas you can think of and feel
free to share any tools you have come across.

Wiki looks quite comprehensive.

Maybe consider this option for createrepo - see if it helps or not:

-c --cachedir <path>
Specify a directory to use as a cachedir. This allows createrepo to
create a cache of check-
sums of packages in the repository. In consecutive runs of createrepo
over the same reposi-
tory of files that do not have a complete change out of all packages
this decreases the pro-
cessing time dramatically.

For bug 527288 Mirek Suchy used some sort of python code analyser,
which was able to find performance issues - this allowed him to clean
up code and improve performance. I do not know what program it was
though - if you want to ask him.


Hi Mirek:

Could you point us to the tool as per cliff's comments.

I wrote about it on satellite-dept during 2009...

From my email:
When you want to profile python, just do:
 import profile
and replace
 sys.exit(abs(main() or 0))
 sys.exit(abs(profile.run('main()', '/tmp/profile.data') or 0))
or similar for any function you want to profile.

yum install tkinter
download http://svn.rhndev.redhat.com/viewcvs/trunk/eng/scripts/pprofui.py
and display the data using:
 pprofui.py /tmp/profile.data

That script is grabbed from:
