Tom, Ankur,

C-u 0 C-x e
repeats the last macro until the bell rings. (C-u nnn C-x erepeats the macro 
'nnn' times).

As previous commentators have said, you are better of with regexps (they are 
lot faster).
Disabling font-lock-mode (or even putting the buffer into fundamental-mode) 
will speed up macros.
