Flickr: The Real World PHP 5 Benchmark

Sebastian Bergmann » 26 March 2009 » in Benchmarks » 1 Comment

Benchmarks such as the PHP / GCC / ICC Benchmark I posted quite a while ago on this blog are synthetic. They test "raw bytecode execution" speed that cannot be translated into real-world situations per se.

Flickr recently migrated from PHP 4 to PHP 5. And here are their real world numbers:

Drop in CPU usage after migration of Flickr from PHP 4 to PHP 5

Wow.

I am looking forward to John Allspaw's slides from his presentation on "operational efficiency hacks" that he will be giving at next week's Web2.0 Expo.

    Wow - that's quite a nice improvement. Maybe the presentation implies that they also made some changes to the source code as to take advantage of PHP5's capabilities?

    Best regards,

    Sebastian Bergmann beschreibt die CPU-Last der Flickr-Server - zu grauen PHP-4-Zeiten und nach der Migration auf PHP 5. Die Statistik von Flickr belegen rund 20 Prozent weniger Last auf Seiten der User-CPU.
