Slow Accessing Webservice Remotely

[daveshep666]

Hi

I have a simple web service written in C# and served through IIS. When
I am repeatedly calling one of the WebMethods, either from the local
machine or on the local network, the server can process about 400
requests a second. As soon as the web service is accessed from the
outside world the figures drop drastically to only 1 per second (from
a single client). I have tried hosting the server on different
hardware and at different locations around the world, but the result
is still the same. Could anyone shed light onto why this is happening
or maybe give some hints on what areas to check to speed this up?

Thanks

Sorry… I forgot to mention in my post, the server is only transferring
a small amount of data per request, Maybe about 4kb, and the internet
connection is very fast on both the server and client. CPU usage on
the server is nearly nothing when it is processing 1 request per
second.

Thanks
