The import of the cgi module takes about 95 milliseconds and the browsers
takes around 260 milliseconds to fetch the xml-page. This is why I thought
it to be important, but I think you are right, I should not worry about
this and switch to another protocol. Is not possible with the current
hosting provider, but I'll switch.
Pointers where to look for in selecting the protocol are apreciated.

Okay, thank you for the explanation.
