The testing machines' hardware is as follows:
CPU: Intel(R) Xeon(R) Platinum 8260 CPU, 96 cores
NUMA nodes: 2
RAM: 1024 GB
However, for another benchmark experiment I'm doing, I booted the machine
with "numa=off mem=16G" kernel command-line. I admit this is an unusual
setup...
On that machine, I create a fresh btrfs with "mkfs.btrfs -d raid0 -m raid0
<devices>" with 6 SSD devices. And, I run the following command on the FS.
fio --group_reporting --eta=always --eta-interval=30s --eta-newline=30s \
--rw=write --fallocate=none \
--direct=1 --ioengine=libaio --iodepth=32 \
--filesize=100G \
--blocksize=64k \
--time_based --runtime=300s \
--end_fsync=1 \
--directory=${MNT} \
--name=writer --numjobs=32
tools/workqueue/wq_dump.py output is pasted at the
bottom. "btrfs-endio-write" is the workqueue, which had many workers on the
unpatched kernel.
FYI, without the kernel command-line (i.e, numa=on and all RAM available as
usual), as shown below, your patch series (v1) improved the performance
significantly. It is even better than the reverted case.
