Compare the following results:
Rebol: 18 seconds
h: make hash! []
start: now/time
n: 100000
for i 1 n 1 [
append h i
]
print ["Elapsed time for" n "records" (now/time - start)]
-----------------------
Python: 0.37 seconds
import time
d = {}
start = time.time()
for i in range(0,100000):
d[i] = i
print 'Elapsed time: ', time.time() - start, ' seconds'
--------------------
PHP: 1 seconds (rounded)
<?php
$start = time();
$arr = array();
for ($i = 0; $i < 10000; $i++) {
$arr[$i] = $i;
}
print("Elapsed time: " . (time() - $start) . " seconds\n");
?>
