[pitrou]

The stringbench suite of micro-benchmarks, currently available through SVN at http://svn.python.org/projects/sandbox/trunk/stringbench, would probably be a reasonable addition to the Tools directory.

[vstinner]

Some ideas to improve stringbench:

• test different Unicode range (stringbench tests only ASCII currently)
• test mixing different Unicode range, e.g. ascii+latin1, UCS2.find(ascii), UCS2.replace(UCS2, UCS4), ...
• add options to configure string lengths

Python 3.3 is now a little bit faster for pure ASCII strings. Python 3.2 is sometimes a little bit slower with non-BMP characters in narrow mode.

I expect different differents on Python 3.3 if we test different Unicode ranges.

The URL got mangled in at least my browser, so I'm repasting it on its own line:

[vstinner]

Please integrate stringbench into the HG repository. I will try to improve after its inclusion.

[pitrou]

What, do you mean, "please"? This is exactly what this issue is about.

I mean that it is a good idea to integrate the tool, I want it in
Python source tree! Go ahead.

New changeset 704630a9c5d5 by Antoine Pitrou in branch 'default':
Issue bpo-13165: stringbench is now available in the Tools/stringbench folder.
http://hg.python.org/cpython/rev/704630a9c5d5

[serhiy-storchaka]

I think that would be a useful tool for comparing two stringbench results. I propose an example of a script. Can use them separately or included in the stringbench.py, it's only an idea.

Please open a new issue for such improvement.

Please open a new issue for such improvement.

Well, I'll do it as soon as slightly improve the script.
