Today we will benchmark about associative array (again) but with lower number of items, since most scripting language failed the previous benchmark. This time we will use lower number of input (only 1% of previous benchmark). The testing done in 64-bit Linux, Intel i3-4150 CPU @ 3.50GHz, 8GB RAM and Non-SSD hard disk. The code can be found on my dropbox (folder: assoc-small).

Note #1: Apparently my previous code for Python, JavaScript and PHP were wrong because I forgot to round the floating point division, I have updated the previous benchmark result.

Note #2: PHP 5.6.5 failed to build the associative array within 2200s

Note #3: I/O JS and NodeJS seems fast to build the associative array, but awfully slow when iterating array
