Hi

We have 4 bonded VPN's using 3G connections - each VPN is using UDP

bond00 - vpn00, vpn01, vpn02, vpn03

Each 3G vpn is capable of approx 1.5mbit/s - and when only one vpn is plugged into the the bond00 (i.e, just vpn00 up) the connection speed through zeroshell is 1.5mbits on the bond00 interface

When all the connections are used in the bond group (vpn00, vpn01, vpn02, vpn03), and downloading a "single" file, the interface speed observed on bond00 is approx 400kbit/s

If we start multiple file downloads (i.e. 20 downloads simultaneously) the bond00 interface speed increases to 5mbit/s - which is more like expected

Why when downloading a single file does Bond00 only work at 400kbit/s when we know it is possible to get up to 1.5mbit/s using just vpn00 or 5mbit/s downloading multiple files


Regards

David

I'm having the same problem to. Could it be the server upload speed the cause of this problem?
