Package: apt
Version: 0.9.5.1
Severity: normal
Dear Maintainer,
I've recognized that "apt-cache search" has become quite slow on my system, and
when stracing it it shows that it lists the contents of /var/lib/apt/lists a
lot (45227 times!):
openat(AT_FDCWD, "/var/lib/apt/lists/",
O_RDONLY|O_NONBLOCK|O_LARGEFILE|O_DIRECTORY|O_CLOEXEC) = 3
getdents64(3, /* 156 entries */, 32768) = 13920
getdents64(3, /* 0 entries */, 32768) = 0
close(3) = 0
% grep -c 'openat(AT_FDCWD, "/var/lib/apt/lists/"' apt-cache-search-strace.txt
45227
(this count is reproducible with a second run)
% time apt-cache search tomahawk
apt-cache search tomahawk 3.84s user 4.54s system 99% cpu 8.427 total
I have reported the bug against Ubuntu at:
https://bugs.launchpad.net/ubuntu/+source/apt/+bug/1004947
I have tested it to be still an issue with apt from unstable.
