Hi,

Indeed  we are experiencing some trouble with network bandwidth on our Lannion node.
The following is a temporary solution, and we are working on a permanent resolution about this issue, that we will implement soon.

In order to get a "good" bandwidth, enter the following command as root user in your instance :

"ethtool -K eth0 tso off"

If needed, replace "eth0" by the actual name of your interface. Once done, you should download  around  70/80 Mbps.

Best Regards,
Erwan for the Lannion Support Team

> Hi,
> I'm working at one of the European Pioneers - Zylia - with FiWareLab.
> We were given access to our resources (particularly some VMs at Lanion
> region). We're running low on time until next weeks demo. We are still
> tweaking our cloud service, and it requires fast network connection as
> we send and download large amounts of data on this VMs. The problem
> is, even if I try to perform simple apt-get update on such a VM, it
> takes ages to download few kB of data. Network speed is terrific and
> it makes working with FiWareLab impossible. Can You do something about it quickly?
