Package: sed
Version: 3.02-5
Severity: wishlist
Regexp performance is woeful:
sed '/^$/d'
takes 5 seconds while
mawk '!/^$/ { print; }
takes only one. Both are running on the Packages file for potato's main
component.
This is already known, in fact it's listed in the BUGS file.
So why am I reporting this? Well, it seems that sed is no longer maintained
upstream as the last release was made 2 years ago. So I'd like to see
someone in the GNU project pick this one up again as it's such an important
program, and we desparately need to improve the regexp performance so that at
least it can outperform gawk if not mawk :)
So could you please contact the current upstream maintainer so that the
status of his maintainership can be clarified? Perhaps you can even start
hacking it :)

This slowness should be fixed already in etch (and maybe even sarge).
Please reopen if you can still reproduce it in current version.
