[mythtv-users] BE slow without internet connectivity

[Tim Draper]

this problem first exhibited itself with slow FE performance when it
first wakes up and interacts with the myth DB (ie: liveTV, recorded
shows, videos). however, it seems that the BE is also slow during
initial connection with SSH (before MOTD/password prompt), and the
same with VNC (asks for password, desktop is displayed, but takes time
to show mouse cursor).

the BE is on 24/7, it runs mythbuntu 11.04 x64, and 0.24.1 as of
around 2 weeks ago.
mythweb seems fine, as does other services installed (webmin &
qbittorrent). file transfers seem fine too.

the problem arose after i lost ADSL connectivity last friday (ADSL
still down), and which my single mythFE also had problems with
ICEauthority when starting the frontend (deleting the .ICEAuthority
file in 'home' fixed this).

i have LAN access, but no internet.
is this expected behaviour? aside from qbittorrent on the BE, there is
no other internet orientated connections i am aware of.
