Bug#179384: apt: Limits of rate-limiting



Package: apt
Version: 0.7.14+b1
Followup-For: Bug #179384

I believe I asked for this fix, long ago. However it appears
to have gotten lost in the mists of time, down the swirl of
the Debian sinkhole...

There is an issue with rate-limiting '-o Acquire::http::Dl-Limit='
-- which is not actually completely worked out, logically.

apt-get does NOT rate-limit the entire download session:
instead, it only rate-limits each particular process it is
working on. And so, when you are getting packages from
_multiple_ sources, the download rate is actually a
*multiple* of whatever is set in 'Dl-Limit='.

This, of course, is NFG for anyone who has set the rate
limit thinking they have set an absolute bar for apt-get.
They will instead max out their Internet connection, if
there is more than one source.


-- grok.
