    40 Mbps is the amount of data that can be moved in one second; the difference between 20% saturation and 90% saturation should have negligible impact on latency. The bottleneck would occur if you OVERsaturate the line (ie. trying to pull more than 40mbps down) because then the packets would need to take turns coming in and possibly even be re-sent from the source if the latency is so bad that those packets are wiped from cache on routers or switches. (FUN FACT: this is basically how a DDOS attack works, too many packets are being thrown at your network and your router can’t say “no” fast enough to the bad data so latency approaches infinity and the good data ends up getting buried as well)


  • Mbps is a measurement for bandwidth not latency. However, it’s a little confusing what OP wants based on the image alone. The question marks in tandem with the bandwidth values makes me assume OP wants to know their outbound bandwidth but they are clearly asking for latency in the post text.













  • Yeah, I gave up because it wasn’t really necessary for me. I have a /29 plus I can open ports so I just decided to set up an SMTP relay on my VPS because my ISP blocks outbound on port 25. I can still do inbound on port 25 so no issues receiving emails. It actually might benefit you to have an SMTP relay on the VPS to properly route the outbound email if you don’t want to have two Wireguard tunnels running.
