I'm tired of massive delay (500-1000 ms pings) while uploading large files. QoS helps some, but a significant portion remains due to bufferbloat (100-150ms). This leads to delay in VoIP calls and generally sluggish web browsing while uploading.
The new Codel algorithm in OpenWRT / Attitude Adjustment should help a lot. The results below show only ~5-6ms of added latency during uploads (i.e. 14ms vs 500+ms before!). Insane.
These instructions are for the TP-Link TL-WDR4300, because I got a good deal. If you have the money, buy a Netgear WNDR3800 and install CeroWRT, you'll probably see even better results.
Why the TP-Link TL-WDR4300
In short, its fully supported in OpenWRT Attitude Adjustment and works well for my needs:

Enable key-repeat for ALL applications or just for IdeaVim/specific JetBrains apps
Upgrading to Lion or Yosemite and WebStorm 9, I noticed key repeat was
turned off for the IdeaVim plugin h j k l keys.
System-wide key repeat
defaults write -g ApplePressAndHoldEnabled -bool false in a terminal will enable
key repeat for every app. This can alternatively be found in the accessibility
settings in OS X' preferences.
setup shorewall for docker networking beyond the default bridge network, e.g., for docker-compose
Docker(-compose) with shorewall
The shorewall documentation explains in http://shorewall.org/Docker.html how to configure shorewall for use with docker. The problem with the configuration is that it only allows connections from the host to the main bridge docker0. Connections to other networks on dynamically created bridges, with names starting by default with br-, is blocked. Instead of the recommended contents of /etc/shorewall/interfaces, use wild-card interface names as follows:
#ZONE INTERFACE OPTIONS
#dock docker0 bridge # disabled default recommendation
dock docker0 physical=docker+,routeback=1
dock br physical=br-+,routeback=1
