Seems similar to this machine when it comes to speed. Perhaps churchill is
a bit slower, but probably bigger. :)

Well, considering that I think about 10 minutes (1 meg/s) is pretty normal
for grabbing an image off the net, and even faster if it is a good
connection and a fast server in the other end. If it goes down under
0.5M/s I start complaining on how slow it is. As I did with the
pseudo-image-kit. ;)

The joys of academic networks and lots of bandwidth. :)

Good luck! :)
