Slow internal speed between SYS servers

After 5 months and +50 tickets and several complains there's no solution yet.
Still no respons on the questions I asked for getting a refund for the months for a not 100% working server, and a false promise of getting a new server at OVH !
I hope some else knows a solution
The problem in short, the upload speed between two SYS servers is not as promised, only get max 90Mbits between two servers.
I see no difference between a server in rescue mode or running a live system.
The other servers we have at SYS are working as promised, see below
