From the evidence of that thinkbroadband website, my upload performance efficiency problem has improved. I was moaning that I wasn’t getting anything like the upload speed expected from calculating it pretty accurately in the sense of deducting absolutely all overheads properly. Also I seemed to remember that a year or so upload speeds were much better.
I was wondering if the poor results were due to incorrect load-share upstream figures per link set in my router, inaccurate because they were out of date for line 3 - the slow-upstream link - whose speed keeps changing. I now have a program that uploads the right numbers into the Firebrick router’s xml config for per-line upstream capabilities, so I ran that to ensure load shares were up-to-date and retested. Results were inconclusive because the TBB speed tester has too much variation in the numbers.
Mind you, that doesn’t have anything to do with IPv6 vs IPv4 upstream of course.
I was moaning tonight because FaceTiming my wife who us on the same WLAN was so rubbish. <rant> The thing must be too stupid to route it properly and keep it inside the LAN I think. I’m assuming that the idiot thing really does go outside and back in, even though we all have global routable IPv6 addresses that clearly show we are in the same /64. And in the case of IPv4 you can tell as well. But in general, why not just ping (metaphorically) dest to try it? </rant>
