Hi,
I have 75/75 fiber, that speed tests max 85/90.
(Both wan and lan ports both confirmed gigabit from system log.)
I set qos to 72/75, as that is well below the limits. Pings never go above 10 ms to google during any speed tests. ICMP and packets smaller than 85 are high priority.
Normal http class I limited down to 70/72, so there is space for any ACKs, priority, etc.
However, when downloading a huge file (linux distro by test), the download speed crawls down to <900 kB/s when uploading at full 70 or so Mbit in speed test. The router cpu load is not maxed out (WNDR3800 @800mhz) and ping -t google.com is showing 10 ms.
Why are downloads being killed, even with so much overhead available? Even at full 70Mbit download, the upload of acks is around 1 Mbit.
I have the same issue with latest trunk openwrt.
I thought that UPLOAD at normal priority wouldn't slow down the ACKs at high priority (which is confirmed to be going there), especially while DL is barely used!?

Re: 75M/75M fiber, download slow when uploading full
So I tried 2 situations... I limited the upload to 60M, it still went below 900 kB/s (about 10mbit).
Then I limited the upload to 45M, same thing.
Then I tried 2 different PC's... one doing the download , then run the speed test.
Same thing.
No idea what is going on, because at limit 60 or 45 cpu is no where near fully loaded, and 45UL+ 10dl= 55mbit...
way less than the 75 ONE WAY limit, even if it were added up!
Both tests run with download uncapped and normal qos limit.

Re: 75M/75M fiber, download slow when uploading full
Just tried the MI424WR actiontec router with default firmware.
No issues when downloading even with QOS off.
When uploading at 75 Mbit or even 80 Mbit, the download just drops a bit, to around 50 mbit.
Even at that time, pings shoot up to 100 ms... still the download doesn't drop to a crawl like it does with openwrt/gargoyle.
Confusing!?!?!???????

The buffalo g300nh even with cpu maxed out qos on doesn't have this issue!
It's the WNDR3800 which is similar to WNDR3700... Stupid WAN port has driver issues:

There's a patch there that works. But I have only been able to apply it to openwrt barrier or trunk... as the AA driver has a bit different syntax. No amount of me trying to match it has got the patch to work right... It compiles but gargoyle doesn't boot properly on the router!
