Filesystem performance on directories with non-trivial number of entires abysmal under Beta 3 and Beta 4.
Finder rountinely locks up for many minutes at a time while listing directories, recursive deletion of files using command line takes minutes to hours with non-trivial directory nesting. Using a rotational hard disk, apfs.
Problem is confined to a single profile.
Booting to a separate volume on same disk with just a bare home directory has no performance problems.
Problem home directory was populated using rsync from existing High Sierra machine (HFS+) — Migration Assistant was exhibiting same abysmal write rates (I'm guessing - estimated time to completion for 700GB was 100s of hours using 1000 BaseT direct connection).
Is anyone else seeing this? Any suggestions on diagnosing problem? Submitting a radar is likely to elicit a reflexive request for a spindump — which is likely to take until release of beta 5 with current performance. I'd like more information before I file a report.
