Re: [Ltib] Problem using LTIB

[Aaron Wegner]

Guys, I have encountered something similar as well.  I took a guess that
it might be ipv6 related, so I disabled that, but really no significant
improvement.  I guessed that because about 2 months ago I tried debugging
the same issue and it seemed like some of the Windows machines here had
more luck with the download rates than my Linux machine was having.  Now I
can't reproduce that behavior.  Today I've tried Windows, Debian Linux,
and Fedora Linux.

I don't know how the handshakes work, but it seems like periodically the
transfer rate is renegotiated, and always to a very low rate.  Now I'm
achieving 5 KB/sec from bitshrine.org.  Other sites work better for me,
about 300 KB/sec from kernel.org.  I have resorted to downloading my
.tar.gz files from other sites on the Internet, but the biggest problem
for me is the toolchain, which I would like to get from bitshrine.org, as
I don't really know where else to look for the exact same files.  100 MB
at 5 KB/sec means I'll have it next week.

Is it possible that bitshrine.org does not allow renegotiation of download
rate often enough?  I don't know enough about it.
