I'm forwarding this to the admin of HEAnet (where apt.sw.be is pointing 
to). Since they are one of biggest public mirrors of free software they 
handle that much load that they fequently run development Apache releases 
in order to test them under these unique conditions.

Since a month or more, I noticed that apt.sw.be sometimes takes a long 
time to have an initial connection. Afterwards everything goes more smooth 
(probably because it is reusing the same connection with HTTP/1.1).

It might have the same cause.
