[Apt-cacher-ng-users] slow "apt-get update" via apt-cacher-ng

[Kirill Timofeev]

Hi folks,

I have vm with ubuntu 14.04. I installed apt-cacher-ng on this machine 
and configured proxy in /etc/apt/conf.d/01proxy:

root at els-trusty-test-02:~# dpkg -l|grep apt-cacher-ng
ii  apt-cacher-ng 0.7.26-1                      amd64        caching 
proxy server for software repositories
root at els-trusty-test-02:~# cat /etc/apt/apt.conf.d/01proxy
Acquire::http::Proxy "http://127.0.0.1:3142";
root at els-trusty-test-02:~# time apt-get update >/dev/null 2>&1

real    0m35.008s
user    0m4.576s
sys     0m0.673s
root at els-trusty-test-02:~# rm /etc/apt/apt.conf.d/01proxy
root at els-trusty-test-02:~# time apt-get update >/dev/null 2>&1

real    0m13.935s
user    0m3.796s
sys     0m0.581s
root at els-trusty-test-02:~#

As you can see "apt-get update" via apt-cacher-ng takes much more time 
than directly. Please let me know if I need to tweak any configs. Also 
please let me know if I need to provide more information.

Thanks,
Kirill.
