Out of interest: a know nothing like me assumes a drive is a drive no matter how its connected. What's different about a NAS drive and a directly connected one?

They're extremely slow at reading small amounts of data from files.  They're decently fast when reading an entire file.

Locally connected drives (USB/FireWire/Thunderbolt/E-SATA) are usually very fast at reading/seeking around in a file.  They're also fast at reading the entire file.

After usning Photomecanics Plus for more than a year, I found it was time to move my 4TB of photos from a USB attached drive to a Synology DS920+ NAS.
The NAS and the drives are chosen so that the NAS it self (drives, processer, ram)  was capable of deliver a good performance. With the Photomecanics catalogs on my PC's SSD drives, I did excpect af decent performance at least when scrolling and searching, as the PM database and thumbnails are stored locally. However - the performance is very poor. There seems to some kind of "lock" between catalog and the data, when disk is attached (mounted via LAN). Working purely dismounted / offline (no data disk /nas attached only browsing throug local catalog) has never been a problem.
I do hope that Camaera Bits can fix Photomecanics Plus perforance in a NAS environment sometime in a not so distant furture. I just love my Photomecanics Plus, that have brought my thousands of photos "back to live".

Correct.  If the files are available, they're used to load metadata, thumbnails and previews.

I would like to make it possible to always use proxies on slow devices (either through a heuristic or via user choice per volume), and even ignore the metadata from the files themselves until it is time to modify them or the files (the image and any XMP sidecar file) have been modified since the images were added to the catalog.  Do understand that when this is implemented, your previews will always be limited in quality to the quality of the proxy images.  Though we could make it so that when desired, the full image could be loaded (though it would once again be slow.)

Unfortunately this is not a simple task and will take some time to implement.  And while I consider it a high-priority issue, there are higher priority issues I have to deal with before I can work on this.

Hello Kirk,
The idea you explained would be exactly what I need. I hope that you will find time to implement it in the near future.
Sincerely,
Nicolas
