| Summary | 0003297: hash_hmac() is slow | ||||||||
| Description |
<?php $message = str_repeat('x', 1000); $key = base64_decode("NMvhzq3jlze/4WlyuRXQ5w=="); $hash_key = base64_decode("CdMQm0q6JeUgalXRwQQZ1h/8WQA7fJh1OuY0xuZooxQ="); $start = microtime(true); for ($idx=0; $idx < 10000; $idx++) { $hash_val = hash_hmac('md5', $message, $hash_key, true); } print microtime(true) - $start; This reports a run time of about 75ms under Zend PHP and about 610ms under Quercus in compiled mode (after repeated reloads to make sure the JVM has properly compiled everything.) |

With the improved performance, Quercus is still slower (by 2x on my system). The time is mostly spent inside the crypto routines. This may be a case where Java is just slower than C for highly numerical calculations. |
