Hopefully somehow maybe while they are in there they might do something to fix the nasty system lockups I have seen when starting both time machine and carbon copy cloner backups since switching to APFS. I'm assuming it is related to having >5 million files, but haven't figured that out for sure.
The symptoms are the system becomes almost totally unresponsive for up to 5 minutes to the point where you can't even drag and drop an existing window sometimes.
- dwaite 7y agoWhat percentage of that do you think is Disk I/O vs lock contention?
- znep 7y agoI wouldn't expect that level of disk IO to cause issues dragging existing windows around without some deeper lock contention or something, it does not behave like just IO bound. Stuff being slower, totally, but not to this level. It was never an issue before the filesystem upgrade.
- sebiw 7y agoWhat physical medium do you use (HDD, SSD)? I had a faulty HDD act up on me like that.
- znep 7y agoSSD on a 2016 macbook pro. The timing coincides exactly with the FS (and OS...) upgrade.
