Package: aptitude
Version: 0.4.11.11-1+b2
Severity: normal
Using aptitude to get information about packages is very slow, and can
often take 3-5 seconds, for example the call:
aptitude show python-twisted
Compare this to
apt-cache show python-twisted
which is in practice instant here.
Stracing the two commands it's obvious that they differ in the amount of
wor they do. Among other things, aptitude seems to read the whole of the
file
'/var/lib/apt/lists/ftp.ch.debian.org_debian_dists_squeeze_main_binary-powerpc_Packages'
linearly. In the strace output of aptitude, it simply opens the file,
seeks to some position and reads what it wants.
Is there a fundamental reason aptitude can't do that?
The major difference (or my perception thereof) between the output of
the two programs is that Aptitude's output is Localized.
