Speed is not the reason to have nothrow as default. It’s so that 
you are forced to be aware of functions that throw and then you 
either handle it or not. With the current status quo you get 
surprise exceptions which is less than ideal. Making nothrow as 
default does not remove your ability to use exceptions as error 
handling, it makes it more reliable.
