PHP Benchmarks

Performance comparison of PHP code alternatives.

Result: Discarded

The test labeled "without @" was the faster by 0.0229 seconds, (2.137% faster)

without @ 100%
@ (shut up) 97.863%

The without @ test took 1.0483 seconds.
The @ (shut up) test took 1.0712 seconds.

Nitty-Gritty

Each test case ran 20 random code order iterations consisting of 271,344 loops for a total of 5,426,880 runs.

  • Line execution difference (0.000004) milliseconds.
  • Avg difference (1.145) milliseconds per 271,344 loops.
  • Total difference 22.89 milliseconds for 5,426,880 loops

The iteration variablity for Code 1 was (6.5457) milliseconds and Code 2 was (5.1120) 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']++;
