| Summary | 0004786: The performance of rantrim on nvme ssd is significantly worse than upstream linux kernel. | ||||
| Description | Recently, I replaced my server's kernel with rocky's 5.14.0-162.18.1.el9_1 (downloaded from https://oraclelinux.pkgs.org/9/ol9-baseos-latest-x86_64/kernel-5.14.0-162.18.1.el9_1.x86_64.rpm.html ). Then I used Fio to perform stress testing on my NVME SSD and compared the performance with Upstream's Linux 5.14.0 kernel. When using the randtrim command, I found that randtrim performed significantly lower in rocky than upstream. The result of IOPS of randtrim on Rocky's 5.13 is around 50k while it is 240k in upstream's kernel. | ||||
| Steps To Reproduce | The running command of fio is below: fio -filename=/dev/nvme0n1 -direct=1 -ioengine=libaio -rw=randtrim -bs=4k -iodepth=64 -numjobs=8 -group_reporting -name=randtrimfob --norandommap --randrepeat=0 --ramp_time=5 -runtime=30 | ||||
