Package: reportbug
Version: 6.3
Severity: wishlist
Hi,
when user specifies the name of the buggy binary then a lookup for the
binary package name is suggested. This is currently done using
dpkg --search ... , which is ok but painfully slow when disk load is
high.
I suggest to use dlocate as primary alternative if dlocate is present.
The justification is obvious, just compare the numbers of syscalls, and
many of them are IO bound:
~ $ strace -f -o /dev/stdout dpkg --search bin/xfce4-keyboard-settings | wc -l
35825
~ $ strace -f -o /dev/stdout dlocate -S bin/xfce4-keyboard-settings | wc -l
3012
Regards,
Eduard.

You are right. dlocate's database was not uptodate and there it was
falling back to dpkg.
Closing, sorry for the noise.
