The default, so... perfpolicy=manual - i dont even know if there's frequency scaling on those minis. Note that when using a real WM (ie xfwm4) with compositing enabled, everything is super smooth, cat'ing /etc/termcap takes <1.5s, moving windows around is okay - if only there was xv support it .. :) Without compositing, moving windows is painful but it has no impact on scrolling/cat'ing /etc/termcap. So the 'slowness' is was seeing was due to fvwm, for completeness will test with cwm. Landry
