The last month or two Lightroom has started to become too slow for my taste ... but is it slow or is it me?

Two examples: I'm viewing a folder and try to scroll the thumbnails, I then have to wait 5-10 seconds (or more) before any scrolling happen. This doesn't happen every time but perhaps 50% of the time. Second example: I view the folders and click on "the triangle" to show sub-folders, sometimes it can take 10-30 seconds before I see the sub-folders.

I haven't noticed this before, or at least not such long delays, it's something that has started to happen this autumn. Editing photos are usually OK and moving between photos usually works OK. I have smart previews set. I've tried to optimize the catalog but it doesn't seem to matter. Since it works OK sometimes I assume it's a caching issue?

My setup is a Mac Mini late 2014, i7, 16 GB memory and an internal hybrid disk. The photos live on an external disk connected via USB3, the catalog is stored on the internal disk. My library contains of about 105000 images, mostly RAW images from a Nikon D700 and a D4s.

Is this what I can expect? Comments?

These wait time are not normal.
Did you optimize your catalog ?
Did you check that your internal disk doesn't have performance problem ? (I hope some Mac expert could explain which log/tool can show that).

Thanks for confirming my suspicions. I've optimized the catalog with no improvement. I've also checked the internal disk using the builtin Disk Utility program but it doesn't find any problems. Hmmmm ...

If it happens infrequently, I would suspect Apple's power saving settings.
I have not had a Mac Mini in years, however Apple used to be very aggressive on shutting down the hard disks, and slowing the CPU.
Before you dig to much in Lr, I would do the easy step of turning off power saving modes in the Mac (I no longer ave one, so you will have to google how).

It is the inconsistent performance, compounded with the scrolling in a folder that raise the red flag. Scrolling through the folder is rather IO intensive, a sudden lag speaks to either a lack of thumbnails (which causes more CPU and disk IO), or the disk needs to come up to speed.

Last note: Make sure you have good backups. Spinning hard disks are start to having increasing failure rates around four years.
