Hi,

I am around SF in CA, and I am using at&t cable modem.

When I ping weinbar.com, I got 50ms, when I ping wizardshosting, it around 200ms. around 10ms for wigloo.com

What influences the speed? the distance between my location and the server location? Or ...

Thanks.

Ping time is mostly a measurement of distance. Not necessarily network performance.

You may very well get better performance from a server that pings 300ms as opposed to one that pings 20ms.

Hehe Weinbar, i just noticed the part in your sig where it says "non-vdi shared hosting" hehehehe can't stop laughing at that. Now non-vdi is a great way of marketing and getting more clients.

Yeah, what he says ;)

To elaborate, signals travel at roughly 200km/ms (2/3 c) and ping measures round-trip time, so the absolute minimum is 1ms per 100km; consider as well that most of the time your packets will be zigzagging across the continent, and you'd be lucky to get a west coast - east cost ping of less than 80 ms.

Similarly, east coast of US - Europe is going to be around 70 ms, even if you are lucky enough to get a direct flight^H^H^H^H^H^H fiber-optic cable.
