Personally, i dont think checking the network path to www.'NSP'.net is the
correct way to do it. To me, tracing the path from multiple locations TO
Exactly. Take SprintLink as an example.
www.sprintlink.net and www.sprint.com are the same box
[martha.commerce.com (188.8.131.52)], but that sits off some T1 somewhere.
www.sprint.net (aka ftp.sprintlink.net) seems to be in a better position
network-wise to determine real network performance.
It's highly unlikely that I'll burn an FE port to stick a web server up --
it's more likely that I'll put the www machine on a shared 10M segment
with other corporate machines.
Also, not everyone will use the fastest machine in the world as their web
server -- expecially for the company (corporate) machine.
www.'NSPs-Customer'.com is better.. altho that doesnt take into account
'peak' times, anomolies, freakish events, position of the moon.. etc..
Hopefully these would be global effects that would show up in everyone's
data - since KeyNote apparently performed the tests from "from 27 major
metropolitan areas in the United States". Oh, does that say 'United
States'? No wonder Bell Canada got screwed.
However, i do find stats kind of entertaining to interpret, i dont think
there is a way to set in stone that by doing X you can find a 'perfect'
value that represents the statistics from A to B.
It sounds like their metric was strictly a 'download time' mertic - maybe
they also took into account the time to connect() - but either way they
are depending on one machine to judge an entire network -- which is a
highly flawed metric. Also, what if it takes 3 GET's to download 50k on
one server, and on another it takes 20 GET's? That is a *huge* difference
in overhead for the server. I wonder how much they thought about their
measuring methods before they decided to implement them.
So how *do* you "correctly" measure a provider's bandwidth and
performance? Well, I don't think there is any simple answer to that
question -- if one at all -- as Mike points out
I'd like to see Keynote publish some details on how, exactly, they
performed the tests - and exactly what tests they performed.
