Reasons to upgrade PHP 5: PHP 4 and PHP 5 performance comparison (1) _php tutorial

PHP 4-07 at the end of the PHP group will no longer support it, so in order to let people more confident transfer to the PHP 5 platform, I specifically did this test, to see if our PHP 4.x really performance than our PHP 5.x better! The test result is obvious, that is PHP 5.x than PHP 4.x, whether object-oriented or process-oriented, is faster than PHP 4.x, so it is necessary to transfer to the PHP 5.x platform, to experience the various functions and performance of the PHP 5.x platform.

Because PHP 5 includes the new object model, more new features, faster processing speed, especially the speed of object-oriented code, although in PHP 4, object-oriented code is more common, But object-oriented code in php5.x is faster than process-oriented, so don't be skeptical about object-oriented performance, as the following test results will show.

test Environment

Cpu	Intel Pentium4 2.66GHz
Memory	1GB
Disk	73gb/scsi
OS	FreeBSD 4.11
Web	Apache 1.3.37
Test tools	AB (can also choose http_load)
Term RPS	Requests per second (number of requests per second)

PHP 4.4.2 Test Results

Functional Function

function signin () { echo "Test"; } Signin (); ?>

Test result: The result of Ab-n 10000-c 50 is 1047.23/rps

Classes Class

Do not instantiate a class

Class user{ function signin () { echo "Test"; } User::signin (); ?>

Test result: The result of Ab-n 10000-c 50 is 1034.98/rps

Instantiating classes

Class user{ function signin () { echo "Test"; } } $user =new User (); $user->signin (); ?>

Test result: The result of Ab-n 10000-c 50 is 1006.14/rps

Inheritance of Classes

Class auser{ function signin () {} } Claāss User extends auser{ function signin () { echo "Test"; } } $user =new User (); $user->signin (); ?>
