Question

Lightroom classic and big catalog ( about 1.500.000 pics)

Hi,

I'm working with a big catalog on Lightroom CC classic.

The problem is that the performances about importing or sync a folder are really slow ( more than 20 minutes to import a new 30 pics folder) and most of the time Lightroom hags during the process and have to forcibly close it.

The scenario is :

- mac pro 4.1 ( 2.66 ghz xeon, 16 GB RAM, SSD)

- osx and applications are on a internal SSD

- catalog is on a dedicated internal SSD disk

- pictures files are on a qNap ( TS-883XU-RP )

- LAN Gigabit with Gigabit switch (configured with jumbo frame) and with all HW cached ports.

- Mac and NAS connected with double LAN gigabit cable (teaming), actually the LAN is very fast

- pictures files are : tiff, jpeg, NEF (average file size 20/45 MB)

What could be the bottleneck ?

It's a lightroom limit or I can get better performances (actually is not so usable) ?

Using lightroom is quite fast, the problem is importing and make a sync (even on a single small folder)

thanks

best regards

IMO it is having the images on a NAS over your network. You could try importing to a local external or internal drive and see how that goes.

I bet it will be very fast.

Hi, the NAS access is really fast. Browsing the same files with Bridge is really fast, so I don't understand

why Lightroom is so slow. I also checked the network data while Lightroom is working and it's not a data trasfer problem, it's using some CPU and RAM, but no data trasfer (because the trasfer is fast).

Maybe the processor is too slow, or with an old architecture. I think new i7 are faster than an old Xeon.

But looking at the system monitor the CPU is never working more than the 20%.

Something in the synchronizing of a folder is causing Lightroom to look through the records of all 1,500,000 images in its database. What that might be, I don't really know, if you have turned off checking for duplicates.

Please clarify ... are you doing imports WITHOUT SYNCHRONIZING the folder, via the Import button, or are you always performing the folder synchronization? If you are doing imports without synchronizing, are these just as slow?

Just a thought, how much free disk space is there on the SSD that has the Catalog and previews files? Make sure it is at least 25% of the total disk space.

I'm not sure I can understand a reason why importing or synchronizing a folder would be slow, but maybe as an experiment you might want to turn off the check for duplicates.

Hi, I already turned off the check for duplicates. Importing seems a bit more quick than making a sync to a selected folder (also with 10/15 images in it). It's really slow and most of the times it hangs and you need to make a force quit.

Hi, yes it's near to be empty. It has more than 80% of free space. This SSD is installed internally in the SATA port, and it's only used for lightroom catalog (and its preview).

Also removing a folder from the folder tree its a tasks that requires a lot of time.
