RAW photos converted to DNG takes a long time

[Benoît Barbier]

Hello,
Sorry for my late reply.

This is version 8.4 of Digikam with SQLite, compiled on Debian 12 
(Bookworm).
To better evaluate the conversion time, there is a date-time string sent 
every second in the log:
“time ------------------- 13/11/2024 19:03:11 ------------------------”.

There are two log files:
1) digikam.log for import with DNG conversion;
https://lufi.ethibox.fr/r/5gekGMbH6R#EeE4S5W5ZzzqlVYssKqr7DBarAXGkiKdWOmJh2a22Fk=
2) digikamBatchQueueManager.log: for conversion (NEF→ DNG) with the 
Batch Queue Manager.
https://lufi.ethibox.fr/r/667BbwSTnp#z9w0FZ7SGOl9OgM507WR3R0ceKzbyG43wyTCnzjuc8c=

I don't have a high-end processor: AMD Ryzen 5 3500U

Based on the number of seconds elapsed during conversion, does this seem 
normal to you?

Thanks
