part of the strace


Hi,

I don't experience the problem, so what do you mean by
"big albums", i.e. how many entries are there?

Also, I had a look at the output of strace, i.e. using
  strace -o/tmp/strace.txt digikam
which is pretty overwhelming
(Even if nothing is done inside of digikam one gets a loop of:
gettimeofday({1192949034, 900696}, NULL) = 0
select(21, [3 5 7 9 12 13 14 15 16 17 18 19 20], [], [], {0, 95}) = 0
(Timeout)
gettimeofday({1192949034, 904522}, NULL) = 0
stat64("/home/abaecker/Pictures", {st_mode=S_IFDIR|0755, st_size=4096,
...}) = 0
gettimeofday({1192949034, 904786}, NULL) = 0
gettimeofday({1192949034, 904832}, NULL) = 0
gettimeofday({1192949034, 904856}, NULL) = 0
gettimeofday({1192949034, 904914}, NULL) = 0
)
Anyway, concerning reading every file: I have an album with
174 images, of which the first 4 are visible in the
album view, and only for these (apart from the initial scan during start-up)
I find an access to the file (see the attachment).
So this suggests to me (but I might be completely wrong)
that only the first few are accessed
(whether they are completely read or not is
beyond my capabilities to interpret the output of strace ...)
