UDP inbound caps on so-you-start servers?

Can you please make sure? It seems unlikely because why would the "IP for UDP" option even exist in the Enterprise plans unless SYS servers have no UDP inbound cap but enterprise servers(the higher tier) have an UDP inbound cap?

I just want to be absolutely sure before ordering a SYS server.

My KS-1 server definitely has a ~45Mbps <=> ~50Mbps UDP inbound cap which can be observed using iperf(sending data to the ovh server) in UDP mode. I originally thought it was much lower but it is caused by massive packet loss as shown below.

// From Ramnode NYC to the KS-1(RBX) => 100Mbps

In comparison to the online.net Server.

The root of the problem seems to be the packet loss from my home connection to the KS-1 server.

Hi,

recently i got a KS-1 kimsufi server and noticed that there are heavy UDP inbound caps applied. Then i read about the option "IP per UDP" which seems to remove this cap but this option is not available for the kimsufi lineup it seems.

Can you please tell me the UDP inbound caps for the so-you-start lineup and if this "IP per UDP" option is available for the so-you-start lineup?

If "IP per UDP" is available for the so-you-start lineup i would also like to know the pricing.
