xfs: increase the default parallelism levels of pwork clientspwork-parallelism_2020-10-26
Increase the default parallelism level for pwork clients so that we can
take advantage of computers with a lot of CPUs and a lot of hardware.
8x raid0 spinning rust running quotacheck:
1 39s
2 29s
4 26s
8 24s
24 (nr_cpus) 24s
4x raid0 sata ssds running quotacheck:
1 12s
2 12s
4 12s
8 13s
24 (nr_cpus) 14s
4x raid0 nvme ssds running quotacheck:
1 18s
2 18s
4 19s
8 20s
20 (nr_cpus) 20s
So, mixed results...
