How fast is a fast PHP script?
<p>This is a question that I can't seem to find an answer for, possibly because on the surface it seems obvious. </p>

<p>I want to know what is considered fast for a PHP script in a commercial environment? "Fast" seems subjective, but there is a definite line between fast and slow, so surely there is an agreed benchmark?</p>

<p>To me if a script took .5 seconds to generate a page then it would be fast, but I think from a computer perspective it is incredibly slow. </p>

<p>It does depend on what you are trying to achieve, but is there a benchmark for PHP speed that should be aimed at? Is there a speed you "shoot for"? What does it take for the scripts speed to be affected by traffic? Can you accurately calculate the server required for a specific application based on forecasted traffic, the speed of the server and the time it takes for a script to execute?</p>
