Not very hard but for 100,000 iterations:
E:\>c:\php\php -q 1.php
0.7458188533783-0.59488701820374
0.74121308326721-0.59862399101257
0.72867512702942-0.58960485458374
0.73737502098083-0.59518694877625
0.73679399490356-0.58968591690063

First number is cumulative time for str_replace, second is for preg_replace. Of
course this is not significant difference for one iteration but how many calls
are in the system?

Also I found one page that says it depends on various conditions:

>>or other string functions. 

preg_match() is a little bit faster than strstr() but the difference is minimal.
