The 3.8.13-6 dev non-release has a trivial patch in it that I hoped would improve 6in4 and 6to4 tunneling performance. I'm not in a position to test at the moment.<br><br>I am curious: Is there a current user of cero using simplest.qos, tunneling ipv6 via hurricane or 6to4, that can hammer it with multiple ipv6 streams (as in the rrul test)? (If you
have rrul and ipv6, you can force it to do pure ipv6 testing with the -6
option.) <br><br>During that test, the output, on 3.8.13-5 and earlier, of<br><br>tc -s class show dev ge00 <br><br>I *think*, will show only a few fq_codel classes in use, rather than one per stream. (you may need to run the command a few times to identify all the streams in use)<br>
<br>It looked to me that the following patch would de-encapsulate the 6in4 stuff for purposes of the fq_codel flow hash calculation, and fix it... (I put this patch into -6 but haven't tested)<br clear="all"><br>---<br>
