Right now, with it still set at 50000, I see 49.86Mb/s from my ISPs' speedtest.storm.ca.

I spend a lot of time ssh'ed into my SOHO desktop from my office, running emacsclient in "-nw" mode. In the pre-CODEL days, this resulted regularly in me getting 20-40seconds ahead of the screen updates. Post cerowrt/CODEL, there were occasional periods of time when codel couldn't protected my typing SSH from the ssh that was running sshfs/rsync. (sshfs/rsync needs to invoke ssh with some option to make it apply DSCP to the packets) I'm think that with 10Mb/s up, I just won't care :-) -- ] Never tell me the odds! | ipv6 mesh networks [ ] Michael Richardson, Sandelman Software Works | network architect [ ] mcr@sandelman.ca http://www.sandelman.ca/ | ruby on rails [
