It is a test on a virtual box Centos 6.4 installation. One forum, powered by phpBB 3.0.11.
I would like to know the time to generate the page.
The time I got is through Firebug on Firefox.
On Firefox 23.0.1, Firebug 1.12.0, Net Panel > All
The waiting time 476ms is the time waiting for the response from web server.
From my point of view it is the time including generate the html.
Which program I tesed on?
phpBB 3.0.11, with file as acm_type. It is a forum viewing page, listing topics of one forum.
How to test PHP and get the results?
I tested seven times on each PHP version. Then took the highest one and lowest one away. Add the five waiting time figures and get the average of it.
Let us see the comparison:
PHP 5.4 with OPcache
PHP 5.5 with OPcache
It is 5% faster when using PHP 5.4 or PHP 5.5.
PHP 5.5 is almost same as PHP 5.4 on loading time.
