[$] Auto-tuning the kernel

The Linux kernel has many tunable parameters. While there is much adviceavailable on the internet about how to set them, few people have the time toweed through the (often contradictory) explanations and choose appropriatevalues. One possible way to address this isa project called bpftune, aprogram that uses BPF to track various metrics about a running system andadjust the sysctl knobs appropriately. The program is developed by Oracle, andis available under a GPLv2 license. Bpftune is currently mostlyfocused on optimizing network settings, but the authors hope that the system isflexible enough to be extended to cover other settings.
