Python is slower than PHP to get Index Position

我惊讶地发现Python比PHP慢，以获得索引位置。有没有一种方法可以提高Python的性能?

例如:

在PHP中:18.169965982437

<?php
$time_start = microtime(true);
$needle = file_get_contents("needle.wav", false, null, 46);
foreach(range(0, 10000) as $num) {
   $haystack = file_get_contents("haystack.wav");
   $match = strpos($haystack,$needle);
}
$time_end = microtime(true);
$finishTime = $time_end - $time_start;
echo $finishTime;
?>

在Python中为:23.6319999695

import time
import math
def microtime(get_as_float = False) :
    if get_as_float:
        return time.time()
    else:
        return '%f %d' % math.modf(time.time())
time_start = microtime(True)
needle = open("needle.wav","rb").read()
for x in range(0, 10000):
    haystack = open("haystack.wav","rb").read()
    match = haystack.index(needle[46:])
time_end = microtime(True)
finishTime = time_end - time_start
print finishTime

对应的python代码如下:

needle = open("needle.wav", "rb").read()[46:]
for x in range(0, 10000):
    haystack = open("haystack.wav", "rb").read()
    match = haystack.index(needle)
