Package: info
Version: 6.8-6
I noticed that "info -w" is puzzlingly slow when the argument is a man
page:
$ time -p info -w ffmpeg-all
*manpages*
real 1.06
user 1.47
sys 0.16
In contrast, "man -w" is near-instantaneous:
$ time -p man -w ffmpeg-all
/usr/share/man/man1/ffmpeg-all.1.gz
real 0.05
user 0.04
sys 0.01
Apparently this is because "info -w" calls "man -a", which is a very
inefficent way to check if a man page exists:
$ strace -f -e trace=execve -o '| grep -w man >&2' info -w ffmpeg-all >
/dev/null
1142 execve("/usr/bin/man", ["/usr/bin/man", "-a", "ffmpeg-all"],
0xfffd7dd4 /* 52 vars */) = 0
