I compiled the new stable longterm kernel 4.9.16 including the new BFQ I/O scheduler yesterday.
BFQ loads programs extremely fast under heavy disk I/O activity. It achieves up to 30% higher throughput than CFQ on hard disks with most parallel workloads, and about the same throughput with the rest of the workloads we have considered. BFQ achieves the same throughput as CFQ, NOOP, DEADLINE and SIO on SSDs.
- BFQ I/O scheduler (Desktop performance improved)
- Phoronix articles, reviews and news stories covering Linux 4.9
- Linux Git log
BTW, I was able to update Fedora 25 Server PPC64 today.
