Description
the subtest expects 50 files each with 1K stripes can be created in 60 seconds which is not quite enough for ZFS. I did local measurements and observed:
- OST object precreation doesn't block creations (MDS has enough objects at any moment)
- MDS needs to update last_used file for each OST object used, i.e. 50*1000=50K times
- ZFS's writerecord and writerecord's declaration is still much slower compared to ldiskfs (2-3x slower)
