I can confirm I am also experiencing this issue. When connected to the
VPN and split tunnelling between the local LAN and the VPN, connections
to both are extremely slow, exactly as described in the above issue.
This issue was not present in previous versions (10.04 and 10.10) and
has only started occurring upon upgrading to 11.04 without any change to
the VPN configuration.
Description: Ubuntu 11.04
Release: 11.04
network-manager:
Installed: 0.8.4~git.20110319t175609.d14809b-0ubuntu3
Candidate: 0.8.4~git.20110319t175609.d14809b-0ubuntu3
Version table:
*** 0.8.4~git.20110319t175609.d14809b-0ubuntu3 0
500 http://gb.archive.ubuntu.com/ubuntu/ natty/main amd64 Packages
100 /var/lib/dpkg/status
As a measure of comparison I've also included the timings for SSH when
the VPN is connected and when it is not (both SSH connections are to a
machine connected to the local LAN).
With VPN:
real 0m16.061s
user 0m0.010s
sys 0m0.000s
Without VPN:
real 0m0.561s
user 0m0.000s
sys 0m0.010s
Both of the above examples are timed up to the moment the enter password
prompt is displayed.
I've attached the apport information for network-manager from my system.
If you need any further information I'd be happy to supply it.
