+### TCP/IP Tuning
+
+A lot of your instance's raw performance is dependent on a properly tuned machine and more specifically, reverse-proxy. We provide support for Nginx and spent a lot of time putting sane defaults in it, but we strongly advise you to follow up with instructions in https://github.com/denji/nginx-tuning as needed.
+
+**On Linux**
+
+```
+$ sudo cp /var/www/peertube/peertube-latest/support/sysctl.d/30-peertube-tcp.conf /etc/sysctl.d/
+$ sudo sysctl -p /etc/sysctl.d/30-peertube-tcp.conf
+```
+
+Your distro may enable this by default, but at least Debian 9 does not, and the default FIFO
+scheduler is quite prone to "Buffer Bloat" and extreme latency when dealing with slower client
+links as we often encounter in a video server.
