PHP Benchmarks

Performance comparison of PHP code alternatives.

Result: Discarded

The test labeled "without @" was the faster by 0.0292 seconds, (4.073% faster)

without @ 100%
@ (shut up) 95.927%

The without @ test took 0.6888 seconds.
The @ (shut up) test took 0.718 seconds.

Nitty-Gritty

Each test case ran 20 random code order iterations consisting of 177,724 loops for a total of 3,554,480 runs.

  • Line execution difference (0.000008) milliseconds.
  • Avg difference (1.462) milliseconds per 177,724 loops.
  • Total difference 29.24 milliseconds for 3,554,480 loops

The iteration variablity for Code 1 was (3.3169) milliseconds and Code 2 was (1.7176) milliseconds. The lower and the closer together there values are the more accurate the results are.

Code

The first test, "@ (shut up)", was:

@$GLOBALS['dummy']++;

The second test, "without @", was:

$GLOBALS['dummy']++;
