Age old question.. count(*), count(id) or count(1) faster ?

Hi,
 No flames.. Have a quick question. I thought this matter be settled but it came up again. Is select count(*) from table faster than select count(id) from table or select count(1) from table faster ? I think all should be equal. ( id is an indexed column by itself in table). I did an explain plan and it came up same for those cases. Or is it not ? am I missing something ? Thnkx in adv.
