In the next few weeks I hope that all maintainers with perl as

their packages as test, or can verify that they don't need to update,

I've built perl-Text-CSV_XS-1.07 for perl-5.18.2 on 32-bit Cygwin.
Functionally, everything seems OK. However, the performance of the test
harness was quite poor. With perl-5.14.2, the perl-Text-CSV_XS test
harness rattled through in 8 seconds; with perl-5.18.2 it was 68 seconds
(same PC) - that's over 8x slower. Is this something you were expecting?
Here are the relevant lines from the cygport log files. Firstly, the
perl-Text-CSV_XS-1.07 test harness running under perl-5.14.2:
All tests successful.
Files=27, Tests=33858, 8 wallclock secs ( 2.23 usr 0.23 sys +
5.05 cusr
2.05 csys = 9.56 CPU)
And now the same running under perl-5.18.2:
All tests successful.
Files=27, Tests=33858, 68 wallclock secs ( 0.34 usr 0.30 sys +
65.66 cusr
2.03 csys = 68.34 CPU)
You can get the perl-Text-CSV_XS-1.07 source from CPAN (or your
favourite Cygwin mirror) should you want to try this for yourself. The
slowest test seemed to be 't/70_rt.t'.
Hope this is helpful,
Dave.
