You can't. pings might give you an impression but even those will only
make sense if there are only a few hops between you and the visitor.

I, for example, got 512kbit cable here. In Switzerland, I got ping
times
of under 20ms to really fast servers and can download with 50kbyte/s.
For fast servers in the USA, I have about 110ms ping times but still
I'm able to download with 50kbyte/s.

Conclusion: there's no such thing as accurate connection speed
detection. The ONLY thing you can do is round trip time measurement
but as pointed out above, this won't tell you much.


Best regards,
 Gabriel
