Following the work on enhancing the scalability of the MQ-Deadline I/O scheduler, Linux storage expert Jens Axboe has applied similar scalability improvements to the BFQ I/O scheduler. Similar to the scalability work on MQ-Deadline, Jens Axboe has optimized the Budget Fair Queueing (BFQ) I/O scheduler to yield better performance. With a multi-threaded FIO test he went from an NVMe drive having 96% locking contention and 86% system time while delivering 567,860 IOPS to around 30% locking contenti...
