[Yum] Header downloads very slow on a Fedora Core 6 machine

[Aad Rijnberg]

Hello,

I am experiencing a strange problem on one of my machines. Once I update this 
machine, downloading of headers is very slow (sometimes 1 kb per minute) 
while the rpm's come in at high speed (>1Mb per second). Could there be any 
explanation for this? (On another machine with FC6 I have no such problems.)

I already posted this message on the yum-devel mailing list, but Seth Vidal 
<skvidal at linux.duke.edu> suggested that I ask this question on the yum 
mailing list. He did mention that it was probably due to an involved firewall 
("it (the firewall) is giving you fits about the byte-range requests.").

Has anybody experienced similar problems? If yes, how can it be solved?
