Measuring latency
Measuring latency
Hi all,
I'm in a unique situation where my landlord can't log in to his router nor is around/cares to contact the ISP to do so. This is my current setup. Does anyone know how I might go about measuring the latency between the router and my end devices (area shaded in orange)? I'm just curious to see how much my setup is introducing in terms of online games and what not.
And yes, 40 mbps is all we get out in suburban Alaska. Cope with me.

You're viewing a single thread.
Why do you need to connect over your Landlord's router, for privacy I would recommend using a VPN but I digress.
Anyway, you can just measure your speed/latency to any near server. I would just Ookla's speed test or any game that has that functionality.
40Mbps is not really much so unless the other devices are using the internet connection constantly you are at no risk. You could also limit other devices speed or set QoS so your PC or console has priority.
This is based on my empirical knowledge, so if anyone can correct me please do so.
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.
Yes, but isn't the 40Mbps a bottleneck? If I have 3 devices with Netflix all at 4k (which supposedly uses 25Mbps) while gaming, won't the latency be affected due to the traffic on the line?.
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)
Fast.com (that's Netflix's speed test) also tests loaded latency, which is basically what you're talking about.
