New router test for bufferbloat Belkin RT3200 Linksys E8450 AX

Yes it's a new router supported

Orange prefixed is /56

The router has ipv6upstream

So it sounds like prefix delegation isn't working for you. Maybe open a new topic for this question, or search the forum to see if you can find someone with similar issues

hello everybody i have compared my hap ac2 with my new router rt3200 the result is amazing

let me know than you think :wink:

I might be missing the obvious, but ~80/20 MBit/s shouldn't put either of your routers to its limits, far from it.

yeah, agreed. These two devices should both have lots of cycles to spare at these speeds. However power saving could be an issue. Also @Dopam-IT_1987 did you use the same SQM speed settings?

I notice quite a bit of difference with the rpi4 compared to the ipq806x... even on 50/15... so guessing a fair bit is tied up in interrupt latencies et. al./scaling-as-above? rather than raw bandwidth... but thats just a random guestimate/2c...

hello, yes i have use the same settings at one details to armv8 i'm use just wan for sqm
but same value speed @dlakelan

i think i will test your script now for see ...

hello everybody i have test fiber optic with rt3200 but with sqm is so poor with sqm enabled , why

this is my result ...

box only http://www.dslreports.com/speedtest/67956979
rt3200 no SQM http://www.dslreports.com/speedtest/67957088
rt3200 with SQM http://www.dslreports.com/speedtest/67957116

On dslreport you are using dsl link
You have to use fiber.

The dslreport's settings like dsl or fiber basically just control how many parallel streams are used. Typically individual TCP tends to 'saturate" before line rate is achieved, so using more parallel streams allow to reach higher throughput; it should not affect the bufferbloat measurements though.
@Dopam-IT_1987 what do you consider poor in these tests, the thoughput (then follow @EXREYFOX 's advice) or the bufferbloat?

@Dopam-IT_1987 what speed do you have on your fiber ISP. 1gig download 1gig Upload

yes my mate has 1gi &gi but is my fault for the test :slight_smile:
1first i have not all connected on the router and not placed to dmz

2nd like you say : i have not see than use the link dsl :confused:

i remake a test for see soon :slight_smile:

good evening everybody

this is my new test with linksys E8450 (rt3200) and is a good news

http://www.dslreports.com/speedtest/67969201 without SQM

and now

http://www.dslreports.com/speedtest/67969397 with SQM

That's a huge amount of bandwidth loss compared to without SQM

yes @dlakelan but it's still suitable, now you have to know if you choose stability or speed :slight_smile:

with fq codel + simple qos

better result than sqm

Do you mean cake

yes fq codel + simpleqos work better than cake and piece of cake

config queue 'eth1'
        option enabled '1'
        option interface 'wan'
        option debug_logging '0'
        option verbosity '5'

2.160 is my console for games

Note, I do not think simple.qos does anything special to CS4...
