Package: apt
Version: 0.9.3
Severity: normal

Dear Maintainer,

Here is how to reproduce the problem:

$ LANG=C time apt-cache policy >/dev/null
1.76user 0.05system 0:01.82elapsed 99%CPU (0avgtext+0avgdata 137200maxresident)k
0inputs+0outputs (0major+11677minor)pagefaults 0swaps

$ LANG=fr_FR.UTF8 time apt-cache policy >/dev/null
0.03user 0.00system 0:00.04elapsed 86%CPU (0avgtext+0avgdata 63584maxresident)k
0inputs+0outputs (0major+5982minor)pagefaults 0swaps

This makes lsb_release very slow because it runs apt-cache with LANG=C, which
in turn makes vmrun, a VMware tool, very slow.

Now the reason for the speed difference between the C and fr_FR.UTF8 cases is
that on my system 'apt-cache gencaches' is being run in the French locale and
that only one cache is kept.

Ideally apt-cache policy should be fast in both the 'machine querying' mode
that's normally done in the C locale, and in the 'main user' locale. Though if
lsb_release should handle things differently that could fix things too.
