Package: apt-cacher
Version: 0.8-4
Severity: important



NOTE: Another user has also reported this problem on debian-isp:
http://www.mail-archive.com/debian-isp@lists.debian.org/msg13260.html

The apt-cacher package works incredibly slow on my system, times
out a lot, and leaves zombie processes adrift in the process table.

Playing with this a bit, during an apt-get update, the first file
usually downloads quickly, then subsequent files will show a download
bandwidth, as they get 10-20 bytes or so of data from the webserver, 
but then will hang for a very long time before completing.  If all apt-cacher
processes are killed (killall -9 /usr/bin/perl, assuming that is safe on
the system) after the bandwidth counter disappears, then the file will
download almost immediately thereafter -- and the next file will encounter
the same problem.

After an apt-get update, the process table still shows a large number of
processes as such:

CGI apache2 support module is loaded and the apt-cacher

I don't know why the below show "not found" for some
packages.  They were installed via dpkg.
