后面又说 op_w_process_latency耗时,都是15ms左右,关键是你有没有队列的 op_w_process_latency这个耗时不会变的吧。③:librbd::io::ImageRequestWQ + op_w_process_latency io延迟应该30ms才对啊。④:看你优化增加rbd_op_threads,iops提高了,但是io 延迟还是15ms左右。 2021-05-18 回复喜欢 ...

The ceph side just has the rbd-nbd reader/writer and its msgr-worker threads set that setting along with mlock (not really needed unless we are doing rbd-nbd swap, but it simplifies the IO path) and oom adjust score to prevent the oom killer from killing us when some other process/driv...
