Hi,
I just tried Gerrit's fix for menu performance. and WOW it makes a huge difference to the speed at which the menus work.
Thank you Gerrit!

Inspired by this I had a thought and compiled navit with -O2 in the CFLAGS (basically switch on all the compiler optimisations) Now my feeling is that this has done wonders for the performance I'm seeing. Though I've not yet had a chance to use it in anger, I was able to set a route and move the map about, zoom in/out etc much more responsively than I felt I had before.

I shall switch back now to regular version and see if I can quantify a difference, or see if it's just me being optimistic. Anyone else care to try compiling with optimisations and see what they think... Gerrit?
