There's this shiny BBR congestion control! It is not universally accepted as a good solution according to Wikipedia, but it is an option to improve TCP throughput in some cases it seems.
This is currently only supported on Fedora and Debian. CentOS 8 also supports it, but we do not yet support CentOS 8.
Create the file
/etc/sysctl.d/71-congestion.conf and put these lines in it:
To enable, use
sysctl --system or reboot.
To verify it is configured properly:
$ /sbin/sysctl net.ipv4.tcp_congestion_control net.ipv4.tcp_congestion_control = bbr $ /sbin/sysctl net.core.default_qdisc net.core.default_qdisc = fq
