PHP Benchmarks

Performance comparison of PHP code alternatives.

Test: sha1 short vs. long

The short string one is 26 characters, the long is 40 times as long (just over 1k.)

Run this test again Return to test menu

Result: Discarded

The test labeled "short" was the faster by 0.0117 seconds, (1.667% faster)

short 100%
long 98.333%

The short test took 0.6877 seconds.
The long test took 0.6994 seconds.

Nitty-Gritty

Each test case ran 20 random code order iterations consisting of 168,700 loops for a total of 3,374,000 runs.

  • Line execution difference (0.000003) milliseconds.
  • Avg difference (0.583) milliseconds per 168,700 loops.
  • Total difference 11.66 milliseconds for 3,374,000 loops

The iteration variablity for Code 1 was (4.9200) milliseconds and Code 2 was (6.1623) milliseconds. The lower and the closer together there values are the more accurate the results are.

Code

The first test, "short", was:

$GLOBALS['dummy2'] = sha1($GLOBALS['dummy_short']);

The second test, "long", was:

$GLOBALS['dummy2'] = sha1($GLOBALS['dummy_long']);
