UDP packet loss inside same data center

Posted On // Leave a Comment

I was running some UDP testing (using iperf3) between my VPS instances. I tried both linode and digitalocean. I was shocked to find a LOT of packet loss! For example, iperf3, udp with 10mbps gave 15% packet loss from london to newyork. Same iperf3 results gave 4% packet loss from london to london (just one single network hop!)


Almost equivalent results for linode and digital ocean. Imagine these are from the top providers!


Is this normal for VPS?! My dedicated servers never did that! (dedicated server germany-dallas, gave me 50mbps UDP traffic without a single packet loss!). Is this a problem with iperf3?
