The key benefit it provides are by using BPF observability features, we can continuously monitor and adjust system behaviour because we can observe system behaviour at a fine grain (rather than using coarse system-wide stats), we can tune at a finer grain too (individual socket policies, individual device policies etc) The problem The Linux kernel contains a large number of tunables;...
