php's future

Hi all in the list : I read an news that said jsp/asp.net is better than php.. They made a test that asp/php/jsp/asp.net using "for loops", Jsp from 1 to 20000 takes only 4 secs Asp from 1 to 2000 (not 20000) takes 72 secs Php from 1 to 2000 (not 20000) takes 68 secs Asp.Net from 1 to 20000 takes only 3.5~3.8 secs... So is it time to learn jsp/asp+ instead of learning php ..??? I am so confused ~ I have been learning php for a while and now it said jsp/asp+ is better than it.@@
