This stack was developed by my colleagues at Netflix (primarily Randall Stewart, known for SCTP). It serves the vast majority of our video and other CDN traffic.
- tiffanyh 5y agoSince Netflix serves (relatively) few but extremely large files, would you recommend using this stack for a typical web server (serving lots of small files)?
- drewg123 5y agoYes. We also use it for non-video small files on our CDN.

- sylwester 5y agoI have been playing with it yesterday night and noticed that I can achieve a throughput of 17.8 Gbit/s on iperf3 with the standard FreeBSD 13.0 stack (in a VM with virtio-net) and only 13-14 Gbit/s on the Rack Stack. Is there something I'm missing?
- drewg123 5y agoRack is not tuned for single stream bandwidth. There are things that it does which may lead to lower single stream bandwidth. For example, if you have 1MB ready to send and enough receiver window, the default stack will loop around in tcp_output() and send all 1MB immediately 16 64K TSOs. I believe Rack will back off in between.
