Re: Darwin disk I/O - better interactive response

You know, if you are concerned about UI responsiveness I don't see how this isn't already handled by the threading priority of CPU tasks. When dragging a window for example, that task is given all the CPU it requires and other tasks which may or may not be accessing the drive would be preempted.

If you're really concerned about responsiveness you would advocate having the window server draw the title and menu bars instead of each application. The window server would handle mousing events in the menu and draw the menus without having to wait for the application to respond to an IPC.

This would also have vast benefits due to the fact the menu structures would be in a central location thus allowing the menu 'bar' to be altered or replaced with anything imaginable.
