This seems to go against all sense, but I figure there is a perfectly logic
and sane explanation behind! ;-)

I take it this was a rather recent libcurl? What OS? What protocol did you
use? Did the server use persistant connections? Did you use SSL? Did you use
FTP?

I guess your tests prove that re-using a handle is not always faster that
init/cleanup in between, but I would say that this is nothing but a rare
exception to the rule.

Or can you or anyone else explain this?
