I have a special performance problem / huge lag when importing from my SD card reader (UHS-I, USB 3.0, card used in a Canon 6D but transfer is over USB cardreader). Reproducably, when selecting some 10+ items and then trying to scroll down (using mouse wheel or scrollbar), the import window hangs for 10-20s, then continues to work normally.
Did you enable some options in Setup/Camera/Behavior dialog page ? I use SD card too with plenty of files : 32Gb SDCard used with a Sony A77. No time latency problem here... Gilles Caulier

The problem was the isSelected(KURL) function. Number of selected items * this function was very time consuming. The selection of 1000 new items has needed more than 20 seconds now no one second. Maik
