hi guys,

Just recently an odd problem popped up on OS X 10.9

Opening bigger directories became awfully slow, like 2 minutes or something.
But only for Movie directories containing mp4s and other video formats in several sub directories, it seems.
The problem seem to be limited to 2 specific directories, both about 1TB in size on a journaled HFS+ volume.
Other directories seem to slower too, but nothing like those 2 dirs.

Repairing Permissions, HD and directory structure did nothing (Apple Disk Utility, Techtool 7)
also rebuilding/ disabling Spotlight index.

The problem is not limited to my account, so it's system wide.
The problem does not exist in a fresh OS X 10.10 setup on another disk.
This started (coincidentally, correlated? ) after  after I had to use Apple DVD player, for the first time since I moved to 10.9, because VLC would not recognize a specific (borrowed) DVD I wanted to watch.

Should I just upgrade to 10.10?
Copy the dirs to another disk and see if it fixes it? Since these are so big, I'd rather do that as last choice.
SMART-Reports of all HDs are Ok.
Any ideas?

SMART unfortunately isn't 100% effective. Could be something wrong with that drive. To rule it out, if you've got another disk on hand you could try cloning your system to it and see if the problem exists there as well. If it doesn't, you might try wiping the first disk and then cloning your stuff back. If it's not a hardware problem, that would probably clear it up. If it is a hardware problem, it'll come right back.

Or, if the issue exists on the second disk as well, it might be time to make a backup, clean install the OS, and migrate your data back from the backup.

I can most certainly can rule out that it's a HD-related thing, since the issue is persistent with the folders backups on different external HDs.
and as I said the problem does not exist when booting from 10.10. I made a test install on an old HD from which I booted.
So I guess, cloning the system drive to make a fresh install and migrate from there, instead of just upgrading might be the best solution.

I got a new HGST 4TB 7K disk a month ago, to migrate from my 3 older Samsungs 2TB 204UI (x2) and 1TB 103SJ.
And since a month the new HGST is running good, so I guess it's safe ot use it.
the 1TB will be used for my system backup now anyway.

If you don't want to upgrade (and I wouldn't blame you, I'm not. No 3rd party TRIM and the new interface is kinda bleh to me), cloning and then migrating your stuff back to a clean install would likely be your best option.

actually I don't have much of choice with upgrading. ;)

Ok, I backuped the 10.9 System to an external HD and thought what the heck, I just upgrade the System to 10.10., if it does not fix the problem I can wipe it and mirgrate back anyway. 20 mins instead to ~5 hours.

And so far I can tell the 10.10. System on the internal HD is as snappy as one can wish for. The slow directory reading times are fixed, problem solved! Though it was a rather unsophisticated approach.

I leave the system and Backup like that for now. See how it holds up.

So thanks for pushing me through the door to finally do another backup of my system :)
