Version: (using KDE 4.1.3) OS: Linux Installed from: Ubuntu Packages Running 64-bit kontact 1.3, on a 4-core system with 4800 bogomips per core, it takes between 10 and 11 seconds to scroll the calendar forward by a single month. Consequently, trying to move backwards and forward and checking the calendar for several months is a rather unpleasant experience, even on a new and fairly fast machine.
