Hi Tom,

I recently upgraded Module::ScanDeps from 0.89 to 0.90 and noticed a big
hit in performance. For me (Windows XP, Strawberry Perl) the following
command:
scandeps -e "use DateTime"
takes about 17 seconds with Module::ScanDeps 0.89 and about 306 seconds
with Module::ScanDeps 0.90.
Commenting out line 262 ( 'DateTime/Locale.pm' => 'sub', ) gives me back
my original scanning time.
I added some debug statements, which show me that scanning takes close
to a second for every single Locale in DateTime. There's 469 Locales
there now, hence the wait.
Is there some way in which I can speed up this process?
Yes. The easy way is to install the newest version of Module.:ScanDeps
from CPAN and use the dependency caching. That means you will only have
to bear with the slow DateTime::Locale scanning once.
Conceptually, if we know the locales don't add any extra dependencies,
we could possible add a special case to prevent it from even trying to
scan the locale .pm files and just add them to the list of dependencies
instead. For lack of time, I can only say: Patches welcome!
Cheers,
Steffen
