What users notice most is latency, not bandwidth.
For example, if every page asset has an extra 1 second latency, then you are adding several seconds to your base page load time as all those 1 second delays stack up. First the main frame has to load, then if you have a subframe, the subframe has to load, then finally the content in it. Nest frames or other content, and suddenly your site seems sluggish for a single user and you're nowhere near your bandwidth limit.
I've had Fios and Comcast and on both latency wasn't great. Latency on their networks varies widely by location and is harder to keep consistent and build a good marketing message around, so they don't sell on latency.
- lsc 16y agothe latency difference between fios and co-lo is going to be tiny. 10ms vs 50ms at most. (yeah, 5x difference, but it's still fifty friggen milliseconds)
- rphlx 16y agoSame for cable.. on TWC I can ping 1,500 miles away in ~60ms. L3 latency is usually a small fraction of the initial website load time. Inline the js + css, strip whitespace, enable gzip, use memcached, get a server that can fit the whole DB in RAM, etc. Preventing packet loss is very important, though (a TCP retrans adds 2-3 seconds). I do think datacenters have a real edge there.
- lsc 16y agopacket loss is pretty huge, and data centers, generally speaking, really are better in that regard.
