forever or infinity from network drive

Is there an existing issue for this?

• I checked and did not find my issue in the already reported ones

Describe the bug

I have a synology NAS and both SMB and NFS enabled
I tried both way to make a collection but it never does, around 5 hours it collects only 250 RAW photos to the collection. But if I copy the entire foldef rom NAS to local nVme it takes just few minutes!

LRC can make colelction from Network Drive like a local drive. why cant Darktable? Whats the obligations?
SMB is running even NFS is runnign wired connection 2.5Gb port can read folder make folder just can not bring the raw file to collection either generating thumb or other option.

Please please fix this.

Steps to reproduce

1. on ubuntu mount your nas via SMB
2. Open Darktable [not snap or app image only vai PPA]
3. import and get to the NAS folder
4. Add photos to collection
5. now wait forever

No source files, tests, or entry points are named. Start by reproducing the import-to-collection steps on an Ubuntu system with an SMB or NFS-mounted NAS, comparing network and local storage behavior. Done means identifying and correcting the cause of the extremely slow network import, with a regression test or reproducible verification where possible.
