Even if that's true, if you have a poor line there is no advantage in
downloading largest first. If the connection fails after 30 minutes you
have wasted 30 minutes of downloading regardless of order. You get the
minimum waste by downloading slowest first. If you take account of the
latency and TCP ramp-up, the slowest transfers are on average the

I run it in a loop.

I've seen some packages fail at ~99% at lot, but not recently. I think
it was a server-side problem that got fixed.

I'd like to see this change too. I don't recall the history of this
with pkg, but in ports it used to work, but fell-off.

I think it just ends-up that way. Actually, when I downloaded distfiles
on dial-up or slow ADSL, I much preferred to leave the largest til last.
Some of the larger ports update frequently, so when you download in
more than one session it minimizes waste.
