Feel free to prove those guessed numbers.

What do you think ? That I implemented copying voluntarily in a slow way ?

This thread is pissing me off because I spent a lot on time on KIO
(and so did Waldo and Stephan) to make it a lot better than it was before
and people throw stones without having any idea what they're talking about,
nor about if there is a real problem.

Doing copying in process in the case of konqueror would be 100% wrong
(because of how much it would keep the konqueror process busy)
but I see some point in implementing in-process get()/put() for apps
that load (potentially huge) files, if it is proven that it is actually a gain.
