This may come as a surprise to you, but libcurl does its very best to perform
all its duties as fast as possible. I promise you, it does not try to make
anything slower than they have to be.

The time it takes is probably because of the name lookup and the connect

I don't think anyone would be happier than me if you could point out how we
could make libcurl perform these issues faster than it currently does.

You can very easily just single-step through libcurl with a debugger when you
invoke the _perform() call, and then you can judge for yourself what it is
doing that is taking all that time.

I'm only human, I might have done something wrong in there.
