    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.















  • What’s the point of renting a VPS if you only access it from your own network? I understand why a large company would do it (risk mitigation) but I don’t understand why a self-hoster wouldn’t just use an old computer at home. Your costs would be reduced and you could more easily control access.

    Now that being said, most Cloud VPS providers have a firewall that you can configure from their web portal. If you whitelist your home network public IP then you can be sure that anyone connecting to your VPS will have to be doing so from your home network. You could do the same thing with UFW or Iptables on the VPS but I recommend using the external firewall because it won’t take resources from your VPS while defending against a DDOS.
