Description S. Burmeister 2009-06-07 11:07:35 UTC 
Version:           0.10 (using KDE 4.2.4)
OS:                Linux
Installed from:    SuSE RPMs

If I use Batch > Batch Raw converter to e.g. convert 50 images on a dual core, digikam only uses one core and processes one picture after the other instead of working on two or more at a time. The conversion of the batch would be a lot faster if it would use all available cores.

If there are concernes that this would slow down everything else, it could be used with "nice" or at least made optional, i.e. offer a checkbox in the batch conversion dialogue to enable/disable it.

sven,

I will not touch Raw converter kipi-plugins in this way...

But digiKam has now Batch Queue Manager where RAW can be converted and more of course :

In this tool, build into digiKam core (it's not a plugin), i plan to use OpenMp library (or another technic) to parallelize queue execution.

Same for the BQM, only one picture is processed at a time.
