mTCP enables high-performance userspace TCP/IP stacks by bypassing the kernel and reducing system call overhead. It was shown to achieve up to 25x higher throughput than Linux for short flows. The document discusses porting the iperf benchmark to use mTCP, which required only minor changes. Performance tests found that mTCP-ified iperf achieved similar throughput as Linux iperf for different packet sizes, demonstrating mTCP's ability to easily accelerate networking applications with minimal changes. The author concludes mTCP is a simple and effective way to improve TCP performance but notes that for full-featured stacks, a system like NUSE may be preferable as it can provide the high performance of userspace stacks while supporting the full functionality of kernel

Infinite Debian - Platform for mass-producing system every secondTaisuke Yamada
Starting from standard install and various "Debian internal" for mass-installation system, the talk goes on to describe generic "instant system generation" which shortens turnaround time from 10s of minutes to seconds. All based on Debian.
Prepared for kickstart meetup of FukuokaDebian.
