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 "long" was the faster by 0.06 seconds, (5.091% faster)

long 100%
short 94.909%

The long test took 1.1188 seconds.
The short test took 1.1788 seconds.

Nitty-Gritty

Each test case ran 20 random code order iterations consisting of 272,667 loops for a total of 5,453,340 runs.

  • Line execution difference (0.000011) milliseconds.
  • Avg difference (3.001) milliseconds per 272,667 loops.
  • Total difference 60.01 milliseconds for 5,453,340 loops

The iteration variablity for Code 1 was (6.4066) milliseconds and Code 2 was (5.0363) 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']);
