pjakma/disable-hardware-prefetch

Tiny script and boot time systemd unit to disable hardware memory prefetchers on modern Intel CPUs. On memory intensive workloads with random access patterns, where there is little locality of data, disabling hardware prefetch can give noticeable performance improvements. It is only possible to disable hardware prefetch globally on a CPU - applying to all programmes running.
