Hi Peter,

I did not try dt 3.4 because it is not yet available in the
repositories of my distro.

This is my hardware:
- CompactFlash SanDisk Extreme 60 MB/s
- Lexar USB 3.0 card reader
- StarTech USB 3.0 ExpressCard
- Pentium P6000 @ 1.87 GHz dual core
- 8 GB RAM DDR3
- SSD drive
It is an ancient VAIO laptop I have upgraded. Not an i7 processor of course.

I tried to increase (512 MB -> 2048 MB) for the thumbnails cache and
the nimber of threads (1 -> 2) without any noticeable effect on the
thumbnails display in the import dialog. No other setting seemed
appropriate.

The import dialog in darktable needs ~18 s to display the 133
thumbnails although Dolphin needs only 2-3 s. So I guess the hardware
is not the most critical point, dont't you?

Laurent
