[Digikam-devel] [Bug 132047] Faster display of images and/or prefetch wished for

[Arnd Baecker]

Ad 1) Well, I didn't believe, and before posting I did
the test with a directory of raw files, however without a look
at the console. And it does feel much slower
to go from the current to the next image than
going back to the previous (or other cached images).
I.e., once they are in cache it works brilliantly!

Looking at the console ouput: it does indeed say that
the next image is preloaded.
However, when going to the next image,
it again says "Running RAW decoding command kdcraw  ...."
on that image (?!) *and* the subsequent image (which is fine).
Sometimes I even observe a kcdraw call for the previous images?
(Just simply going through a bunch of images from the first to the last,
in F3 preview mode, "Embedded preview load full image size"
in the "Album Settings")

Maybe I am interpreting the output incorrectly?

BTW, how large is the cache used for all this (is its size configurable)?

In general, I know that you have been working very hard on this,
and the improvements are brilliant and very much appreciated
(All this, including 2) and 3) look technically rather involved!).

Thanks a lot, Arnd
