Why I did it Fix similar issue seen on #13739 but only for DCS-7050CX3-32S How I did it Add a kernel parameter to tell libata to disable NCQ How to verify it The message ata2.00: FORCE: horkage modified (noncq) should appear on the dmesg. Test results using: fio --direct=1 --rw=randrw --bs=64k --ioengine=libaio --iodepth=64 --runtime=120 --numjobs=4 with NCQ READ: bw=26.1MiB/s (27.4MB/s), 26.1MiB/s-26.1MiB/s (27.4MB/s-27.4MB/s), io=3136MiB (3288MB), run=120053-120053msec WRITE: bw=26.3MiB/s (27.6MB/s), 26.3MiB/s-26.3MiB/s (27.6MB/s-27.6MB/s), io=3161MiB (3315MB), run=120053-120053msec without NCQ READ: bw=22.0MiB/s (23.1MB/s), 22.0MiB/s-22.0MiB/s (23.1MB/s-23.1MB/s), io=2647MiB (2775MB), run=120069-120069msec WRITE: bw=22.2MiB/s (23.3MB/s), 22.2MiB/s-22.2MiB/s (23.3MB/s-23.3MB/s), io=2665MiB (2795MB), run=120069-120069msec |
