Benchmarking PHP 5.5 Beta 3: Not Too Much Over 5.4
Written by Michael Larabel in Free Software on 11 April 2013 at 09:47 AM EDT. 1 Comment
PHP 5.5 Beta 3 was released today wotj a few bug-fixes and other minor changes. To complement the PHP benchmarks earlier this week, here are some benchmarks of the forthcoming PHP 5.5.

The PHP benchmarks covered earlier this week were Benchmarking The Performance Of PHP 5.5 and Facebook's HipHop 2.0 Virtual Machine Is Very Fast. The tests earlier this week found PHP 5.5 to be not too much better than PHP 5.4 when it comes to the performance and memory consumption in a stock configuration (when dealing with the new Zend Optimizer+ and other options, you will most likely be able to tweak additional gains).

With PHP 5.5 Beta 3, I happen to have some new benchmarks from this release on a different system. Benchmarks happened from a CompuLab Intense-PC with an Intel Core i7 3517UE and was running Ubuntu 13.04 with the Linux 3.8 kernel.

Here's the results (see the articles from earlier this week for more details on the tests):

PHP 5.3.23
DETAILED_SYSTEM_INFO:          0.104 seconds
LIST_AVAILABLE_TESTS:          0.333 seconds
LIST_AVAILABLE_SUITES:         32.886 seconds

RESULT_FILE_TO_TEXT:           7.086 seconds

DUMP_POSSIBLE_OPTIONS:         0.003 seconds

ELAPSED TIME:                  315.718 seconds
PEAK MEMORY USAGE:             49.75 MB
PEAK MEMORY USAGE (emalloc):   48.763 MB

Overall, for the Intel Core i7 "Ivy Bridge" system, there isn't much better performance with PHP 5.5 (Beta 3) over PHP 5.4 in this benchmark, similar to the results shown earlier this week. Meanwhile, Facebook's HipHop HHVM is a heck of a lot faster than any modern PHP release.

Details on PHP 5.5 Beta 3 along with download links can be found at Also released are PHP 5.4.14 and PHP 5.3.24.
