in thread selecting columns from a tab-separated-values file

It took 60 seconds to pass 10M (M=million) records.

Hm. 10e6 in a minute suggests a total time for 1e9 of well under 2 hours.

This post mentions a time of 5 hours. What changed?

    The number of fields being extracted, mainly. My example of three fields was just a simplified illustration of my question.

[Corion]: marto: Ow, no, that doesn't help at all :)
[choroba]: Related to the new release, anyone could explain this or this tester report?
[Discipulus]: hello crew! marto thanks for the message: but I how can I help? i'm testing cpan Padre atm problem with Client::Debug
[choroba]: I don't happen to have 5.10.0 nor 5.8.5 handy...
[Corion]: Hmm - I would say the 5.8.5 is a broken installation / corrupt tarball download, and the 5.10.0 is really weird, and maybe a bug in that version of Perl
[Corion]: I don't see how my $result = eval q{'abc' =~ ?b?}; could create a "Modification of read-only value" error
[marto]: Discipulus the issue that should be adressed is that the page needs to be updated to reflect modern perl on Windows
[Discipulus]: but is really necessary to support these ancient versions? from 5.14 onward is not enough?

    Should cpanminus be part of the standard Perl release?
