[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hi,

about nine months ago, Jan (Kara, SUSE) reported a throughput
regression with BFQ. That was the beginning of a fruitful dev&testing
collaboration, which led to 18 new commits. Part are fixes, part are
actual performance improvements.

Jia Cheng Hu (1):
  block, bfq: set next_rq to waker_bfqq->next_rq in waker injection

Paolo Valente (5):
  block, bfq: use half slice_idle as a threshold to check short ttime
  block, bfq: increase time window for waker detection
  block, bfq: do not raise non-default weights
  block, bfq: avoid spurious switches to soft_rt of interactive queues
  block, bfq: do not expire a queue when it is the only busy one
