David Stephen Miller (born November 26, 1974) is an American software developer working on the Linux kernel, where he is the primary maintainer of networking and the SPARC implementation, and is also involved in other development work. He is also a founding member of the GNU Compiler Collection steering committee.
As of August 2016, Miller is #2 by number of commits to the Linux kernel, with 7755 commits since 2005.
He worked at the Rutgers University Center for Advanced Information Processing, at Cobalt Microserver, and then Red Hat since 1999.
Miller ported the Linux kernel to the Sun Microsystems SPARC in 1996 with Miguel de Icaza. He has also ported Linux to the 64-bit UltraSPARC machines, including UltraSPARC T1 in early 2006 and later the T2 and T2+. As of 2010 he continues to maintain the sparc port (both 32-bit and 64-bit).
In April 2008, Miller contributed the SPARC port of gold, a from-scratch rewrite of the GNU linker.
Miller is one of the maintainers of the Linux TCP/IP stack and has been key in improving its performance in high load environments. He also wrote and/or contributed to numerous network card drivers in the Linux kernel.
David delivered the keynote at netdev 0.1 on February 16, 2015 in Ottawa. He also delivered the keynote at Ottawa Linux Symposium in 2000, and another keynote at Linux.conf.au in Dunedin in January 2006.
He gave a talk on "Multiqueue Networking Developments in the Linux Kernel" at the July 2009 meeting of the New York Linux Users Group.
