I'm experiencing some significant OS X lag when listing directories/files. I originally thought it was purely an issue with Finder, and not the HD or any other part of OS X, however I have since noticed some file access lag with other apps, such as Versions and The Unarchiver, so I really have no idea where the problem lies.
The lag predominately appears to be when listing directories/files in Finder, where I'm seeing anything up to twelve or so seconds of lag (the folder opens with a blank list and the spinner going in the bottom right).
- This happens on two different (albeit very similarly configured) computers
- This happens with both the local SSD and network drives (connected via ethernet or wifi)
- Browsing both local and network drives in terminal and listing directories is instant
- I can actually browse files on my NAS from my phone over a 3G connection from the other side of the country faster than Finder can while connected to the local network
Can anyone help? Thanks.
After testing with the
fs_usage command, it appears to be launchd that's slowing things down. These two lines appeared just after opening two directories that took a very long time to list:
13:23:58.528825 select S=1 4.493972 W launchd.1347 13:24:58.572283 select S=1 9.954218 W launchd.1347
fs_usage log with some additional entries:
