3 times x is 3x. Tripling the stampede on a busy server for a dubious
increase in personal speed is kind of rude, from the mirror manager's
point of view. The 'ftp accelerators' that divvy up a download into a
hundred ftp range requests is pathological enough to deal with.

Before this work proceeds, can we please see some hard numbers, and
get some input from mirror managers? Remember that the project relies
in great part on the generosity of the institutions that provides
mirrors.
