Bypassing the Linux kernel for high-performance packet filtering
In two previous posts we've discussed how to receive 1M UDP packets per second and how to reduce the round trip time. We did the experiments on Linux and the performance was very good considering it's a general purpose operating system.

End of the m0n0wall project
on this day 12 years ago, I have released the first version of m0n0wall to the public. In theory, one could still run that version - pb1 it was called - on a suitably old PC and use it to control the Internet access of a small LAN (not that it would be recommended security-wise). However, the world keeps turning, and…

System design implications of declining network latency vs. disk latency
Hardware performance “obviously” affects software performance and affects how software is optimized. For example, the fact that caches are multiple orders of magnitude faster than RAM means that blocked array accesses give better performance than repeatedly striding through an array.

Will there be a Distributed HTTP?
One of the things that came up at the HTTP Workshop was “distributed HTTP” — i.e., moving the Web from a client/server model to a more distributed one.
