Improve latency of VPN service
Look into ways to reduce the latency of the VPN service. We should be able to get 120ms or so from the UK, but currently, it spikes to > 400ms at times, and is rarely below 200ms.
Originally this issue was about installing mosh to workaround VPN endpoint slowness. Better to attack the problem directly (thanks @briann)
Original description
The Geo testbed is only available through VPN. And when connecting to those nodes over ssh, the connection is rather slow (~200ms lag according to @nick.thomas).
As alternative I would suggest to install mosh
(https://mosh.org/) on the fleet. This does not fix the lag, but makes typing feel more responsive.
@nick.thomas already installed it on the Geo testbed primary (using sudo apt-get install mosh
), but not yet on the secondary. Probably also other nodes can benefit from this.
