Is the 100K maximum a hard limit imposed in code, or a
"best-practice"?  (I've looked in a few places and it seems that it is
not a hard limit.)

Currently I go with a trial-and-error approach.  :)

(I'm struggling to get AFS to go over the 50MB/s, i.e. half a GigaBit,
bandwidth...  My target is to saturate a full GigaBit link...)

Thanks Mark for the info,
Ciprian.
