Beachball aside, why does it take 100 billion cpu clock cycles to switch from one tab to another? Because 90% of those cycles are spent in other processes while your kernel is waiting for your blocking I/O to finish, and 5% or more of the rest are taken by the kernel to let other tasks run. </pedantic>
