I'm not really convinced by my patch. It looks like a quick hack. Nick's PEP
432 looks more promising (in speed), simple and safer. So I prefer to close
this issue.

Updated patch: continue to simplify the config parser. Using this patch, Python
startup is ~20% faster on my computer.
Use http://bugs.python.org/file24447/bench_startup.py to measure startup time.

New submission from STINNER Victor victor.stin...@gmail.com:
On my laptop, start Python compiled in debug mode takes 600 ms. Half of this
time is spend in the site module. And most of this time is spend in load the
sysconfig module, which parse sysconfig.cfg, just to get the user site packages
STINNER Victor victor.stin...@gmail.com added the comment:
To speed up python -s, the following patch avoids loading the sysconfig module:

The site.getusersitepackages, site.addusersitepackages and co. functions all
call one function which makes sure site.USER_SITE is set according to envvars
and command-line options; under python -s, addusersitepackages will not add the
user site
