Hi... I used your script and my results are different from yours. The post-while increment is generally the fastest result on my machine (Core 2 Duo, php 5.2.1 and apache 2.2.4). I ran the script multiple times: [schnipp ] For pre-increment (100000): 0.066 For post-increment (100000): 0.066 While pre-increment (100000): 0.028 While post-increment (100001): 0.025 [schnipp ] Greetings Mario
Well, myh results are a little bit confusing again, if using pre-increment, for shows up faster now. But while post-increment is the fastest :) Is there any logic why we all have different results? does it has to do something with the type of CPU, i'm using AMD Athlon. 1800+ (clocked down from 133 to 100 * 11.5) For pre-increment (100000): 0.026 For post-increment (100000): 0.030 While pre-increment (100000): 0.029 While post-increment (100001): 0.023 Tijnema ps. @ Mario: Youre C2D got owned by a AMD 1.15Ghz :)
