How fast is pp/PAR::Packer at packing DateTime::Format::ISO8601 for you?

Anonymous Monk has asked for the wisdom of the Perl Monks concerning the following question:

If you have pp/PAR::Packer, how long does this take?

perl -le " print ~~gmtime "
pp -e " use strict; use warnings; use Getopt::Long; use DateTime::Form
+at::ISO8601; print qq{$_\n} for %INC; "
perl -le " print ~~gmtime "
[download]

On my old laptop it took 32min at 98% cpu usage

It doesn't seem to get faster (on second run) even after adding -cd pp-scandeps-cachefile which has about 2084 files

I thought, hey, the cache does md5summing, all that md5summing is taking extra time, so I produced this patch

But that doesn't seem to speed anything up (I killed it after 9min)

Ideas?

The program runs in ~1 second (perl -e ... ) like you'd expect, its the packing that takes forever -- if something else was slowing things down, the running would take forever also	[reply]
