That's really hard to argue with. An fq_codel same conditions (and pfifo and pie) might be interesting here. On Thu, Nov 30, 2017 at 9:13 AM, Georgios Amanakis wrote: > I gave high RTT with high bandwidth a try: > server -- delay -- mbox -- client > netserver 300/300ms 45/900mbit flen

All this testing has inspired me to go pick up a cheap ($500!!!) 12 core Xeon box I found on craigslist, this afternoon. I'm tired of napping through kernel builds, and needed a space heater. If anyone else could use a build box and sim station pls send me a ssh key. I'd like to get some mips/ar

To correct myself, fping did not die prematurely, it was getting no responses from the remote host because its p parameter was too short at default for an RTT of 600ms. After looking at the source, I realized that it is affected but the s parameter of flent, and changed that instead. On Nov 30, 20

If you use netem to simulate the physical link, you could test Cake's ingress mode downstream of it. - Jonathan Morton ___ Cake mailing list Cake@lists.bufferbloat.net https://lists.bufferbloat.net/listinfo/cake

Re: [Cake] cake flenter results round 3

I would like to point out what Pete said: in my setup the mbox shapes both uplink and downlink with cake, which is mostly untrue in the real world since the router has no control of the downlink. How can we simulate this better? On Thu, Nov 30, 2017 at 1:13 PM, Jonathan Morton wrote: > Looks o

Re: [Cake] cake flenter results round 3

High RTT with relatively high bandwidth is traditionally considered challenging, and is representative of Australasian and satellite connections. Definitely do some of those. Low bandwidth should also be interesting. DSL at 4/1 Mbit is typical entry level package here. - Jonathan Morton ___
