Subject: [Cerowrt-devel] htb and fq_codel performance optimizations upstream
Date: Sat, 11 Jun 2016 11:40:55 -0700 [thread overview]
Message-ID: <CAA93jw4Q7XjvfFf-N61JGBHkmDHy=ZCARL9UYxXCyqA=deppVA@mail.gmail.com> (raw)
So I pulled net-next today to get:
https://www.mail-archive.com/netdev@vger.kernel.org/msg114172.html
and saw that Eric Dumazet has been going to town on reducing lock
contention for htb and other qdiscs. It is always entertaining to do a
"git log"
and search for his name....
I especially liked the ksoftirqd related patch
3bcb846ca4cf55415d3719e64bb45a124792c589
" Depending on qdisc setup, I observed a gain of up to 19 % in qdisc
performance (1016600 pps instead of 853400 pps, using prio+tbf+fq_codel) "
