bpftune aims to provide lightweight, always-on auto-tuning of system behaviour. 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).

Hypothetical Indexes for PostgreSQL. HypoPG is a PostgreSQL extension adding support for hypothetical indexes.
An hypothetical -- or virtual -- index is an index that doesn't really exists, and thus doesn't cost CPU, disk or any resource to create. They're useful to know if specific indexes can increase performance for problematic queries, since you can know if PostgreSQL will use these indexes or not without having to spend resources to create them.
Perf Track is a project that aims to track and measure the performance of sites that use popular JavaScript frameworks and libraries. It is not an exercise to compare the performance of frameworks against each other.
