I do not disagree or something. Just wanna point out one important part, that MANY people still believe is true. The raw speed in DL/UL of your connection does not say anything about the quality or RTT of your connection. Not at all. Otherwise I couldn't have played Unreal Tournament or Quake in 1999 on ISDN with good pings etc. ANd ISDN had what? 128k channel bundling or 64k single channel, still I had 40ms latency to good servers. More important things later on for DSL was not the raw speed, that was irrelevant, things like Interleaving and Fastpath was more of an importance to good/fast connections.
When I switched from ISDN to my first DSL connection I had to mess with Interleaving, which made data in a particular sequence to maximize the throughput of raw speed (there was more to it but that is just one example), therfore you could say, the higher raw speed of my connection was not good for my overall connection quality for gaming, ISDN I had like 40ms, DSL with Interleaving I had 110-150ms. And I had to wait a very long time before my ISP wanted to disable it and use Fastpath.
SO long story short, there is lotf of stuff that has an impact on your latency, like error correction protocols, peering, routing, reliability in general (WiFi vs wired), technology used (DSL, cable, fiber whatever), hardware too. The RAW speed, which most people base their decision making on when ordering a connection at an ISP, actually not.
It is really astonishing how often I see people on the Internet arguing about latency with their connection speed alone. It makes no sense.
