The recent bql-31 build is available for the bold. This build incorporates work from the Linux 3.3 kernel as well as a number of known queue disciplines (qdisc) that dramatically relieve bufferbloat. We believe the DNS/bind and IPv6 code are also working well. The build may have bugs and may not perform perfectly, but it is certainly better than the stock firmware or other builds. We’d like to get it in the hands of people who’re willing to report problems (or successes!)
The Wiki page has information about downloading, installing, and configuring the build.
