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.

VP9 encoding/decoding performance vs. HEVC/H.264
A while ago, I posted about ffvp9, FFmpeg's native decoder for the VP9 video codec, which significantly outperforms Google's decoder (part of libvpx). We also talked about encoding performance (quality, mainly), and showed VP9 significantly outperformed H.264, although it was much slower. The elephant-in-the-room…
