After a reboot, the first search using
Unity Dash will be slower (15 sec) than the second search (seems instant), on my system at least. I guess this is because
file index is cleared after a reboot and recreated as soon as first
Unity Dash search is done.
If this is the case, auto-recreating index at system start-up should work. I could imagine for example automatically running some command at the system startup for gathering info before it is requested by user via Unity search.
I'm interested particularly in searching for programs.
I have disabled
online search for better performance while no interest in that.
