So I finally replace my DI-624 piece of junk with the WRT54GL and it has been fantastic. No more disconnects through the day!!! Anyway, I have a question about QoS:

I ran a speed test and got my up/down numbers and plugged them into QoS. 6500kbits/s down, 420kbits/s up. Those are 95% of the lowest figures I got running the speed test. Last night I decided to try and max out my upload and play a game, to see how QoS handles the traffic (I setup dst port 27015 as high priority and torrents at lowest priority). I took off the cap of 15kB/s upload in uTorrent and let it go as fast as it can and then fired up team fortress. At first, my ping was 300ms. I then lowered the upload speed of 420kbits/s in QoS to something like 380 and got my ping down to 55ms. No matter how much more I lowered the upload speed, my ping would not go below 55ms. Then I put the cap back on uTorrent and my ping went down to 26ms (what I usually ping on the server). uTorrent was pretty much the only program uploading so I had plenty of free upload speed when the ping went down to 26ms.

My question is, is the ping being twice as slow a result of the extra processing necessary to prioritize traffic when it is maxing out the value you plug into QoS? Thx!

Even though processing and filtering packets does create some overhead, a 100% latency increase normally is not produced by it alone.

A lot of the latency and bandwidth issues are created by what type of bandwidth shaping you are doing. Not all ways of doing QoS are equivalent and like most things in the computer world, you have to sacrifice one thing for another. In this case you want to maintain latency low for a game even while uploading a torrent at full speed and apparently the way that your router is doing QoS is not the best way for it.

Hope the info helps.
