<div dir="ltr">Hello, thanks for all of your replies.<div><br></div><div>First of all, my connection <span style="font-size:12.8px">encapsulation should be ATM LLC and it</span> can actually reach up to 17.5/1 Mbps, but that's kinda best case scenario which is why I wanted to play it safe with just 16/.9 (which I should reach more consistently).</div><div><span style="font-size:12.8px"><br></span></div><div>Back to the Steam issue. Unfortunately I can't seem to get really consistent results, mainly because sometimes it's downloading the game from just a few connections and other times it's downloading from dozens and dozens connections. The latter is the one giving me more issues both in terms of latency/packet loss and in terms of evenly splitting the bandwidth across the hosts.<br></div><div><br></div><div>One thing that seems to give better results is changing the interface where Cake is used from eth0 to pppoe0. When I used fq_codel it seemed to give better results when using eth0 and so I went ahead and did the same with Cake.</div><div><br></div><div>Anyway more testing needed, will report if I notice any consistent result.</div><div><br></div><div>By the way this is the thread I opened on the Ubiquiti forums talking about this issue (not sure if it can give you some more info): <a href="https://community.ubnt.com/t5/EdgeMAX/Smart-Queue-seemingly-not-working-for-Steam-downloads/td-p/1890405">https://community.ubnt.com/t5/EdgeMAX/Smart-Queue-seemingly-not-working-for-Steam-downloads/td-p/1890405</a></div><div>Also the thread where I got Cake for the ER-X from: <a href="https://community.ubnt.com/t5/EdgeMAX/Cake-and-FQ-PIE-compiled-for-the-EdgeRouter-devices/td-p/1679844">https://community.ubnt.com/t5/EdgeMAX/Cake-and-FQ-PIE-compiled-for-the-EdgeRouter-devices/td-p/1679844</a></div></div><div class="gmail_extra"><br><div class="gmail_quote">On 20 April 2017 at 20:36, Sebastian Moeller <span dir="ltr"><<a href="mailto:moeller0@gmx.de" target="_blank">moeller0@gmx.de</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><span class="im HOEnZb"><br>

> Just did quick test with your settings. First thing I noticed is my final download bandwidth is about 12Mbps, Steam on PC1 downloads at 1.4-1.5MB/s while downloading a file on PC2 seems to max out at ~250KB/s. From my understanding I should see each PC download at ~700KB/s, or am I mistaken?<br>
<br>
</span><span class="im HOEnZb">Assuming you measured good put in [M|K]iBytes this adds up to 1.5+0.25 = 1.75 * 1024^2 * 8 = 14680064 Bits or (1.4+0.25) * 8 *1024^2 / 1000^2 = 13.84 Mbps which seems a bit high for a 16Mbps ADSL link. I would ecpext something like 16 * (48/53) * ((1500 - 8 - 20 -20) / (1500 + 32)) = 13.73 Mbps TCP/IPv4 goodput… so you seem to be running close to theoretical maximum of your link (assuming I am not totally off with the overhead (estimated ADSL overhead on top of MTU: 6 destination MAC + 6 source MAC + 2 ethertype + 3 ATM LLC + 5 ATM SNAP + 2 ATM pad + 8 ATM AAL5 SAR 32 bytes). But with your shaper set at 15Mbps without the atm option you will actually accept up to 15 * (53/48) = 16.5625 Mbps on the wire, which probably is above your link bandwidth. This fits well with the really low number of drops in your cake stats, you simply never have cake feel that shaping is needed?<br>
