mobile

I hid the search bar on Trebuchet. Google Now is disabled, tool. When I swipe up from the home button to open the Google search, it takes one or two seconds (which is really long in daily use) until the search window appears. When I repeat this shortly after, it starts instantly. I seems to be still loaded in RAM or something.

I remember the search window opened always instantly sometime ago. Has there been an update? Or does anybody know how to run Google search in the Background without the search bar? Or can someon verify this behaviour on his Nexus at least?
