EDIT: This has been because of bug in my code (probably), after debugging and adding checking for correct response in my tests, test prove NO difference (what irks me a little), more in my own answer below.
/EDIT
Hello,
I've written myself a little CSS wrapper for SASS for PHP and programmed it to accept filename and possible flags before running (and possibly caching, if not flagged otherwise) my SASS file.
I've also conducted few test and version nr. 2 is something around 2x - 4x slower than version nr. 1, although version 1 has to run more code then version 2 (It does straight include from disk, rather than parsing URL first for flags).
I don't understand it why really and tests are somewhat too consistent to call it on a disk access overhead.
Here are speed tests:
First - generate file, then - just require from cache
Version 1 total: 10.886 s avg: 10.886 ms/file first: 466.42 ms
Version 2 total: 21.235 s avg: 21.235 ms/file first: 14.54 msJust require from cache
Version 1 total: 7.886 s avg: 7.886 ms/file first: 2.93 ms
Version 2 total: 21.657 s avg: 21.657 ms/file first: 6.98 msVersion with readfile instead of require
Version 1 run 1: total: 7.915 avg: 7.915 ms/file first: 2.49 ms
Version 2 run 1: total: 9.508 avg: 9.508 ms/file first: 3.23 ms
Version 1 run 2: total: 1:17.137 avg: 7.714 ms/file first: 4.61 ms
Version 2 run 2: total: 1:15.717 avg: 7.572 ms/file first: 2.69 ms * - run 2 was 10,000 calls.
Version 1

function is_option($opt) { global $url_options; return in_array($opt,$url_options); }
function fail($message) { echo $message; die(); }
//prepare options array
$options=array();
$url_options = @explode('_',basename($_GET['f']));
if (!is_array($url_options))
{ fail('Wrong parameters given (or parameter can\'t be accepted)'); }
$loadfile = array_shift($url_options);
if (!file_exists('source/'.$loadfile.'.sass'))
{
if (!file_exists('source/'.$loadfile.'.scss'))
fail('Wrong parameters given (file doesn\'t exist)');

$options['property_syntax']='scss';

$css_file = 'cache/'.$loadfile.'.css';
if (file_exists($css_file) && !is_option('no-cache'))
{
header('content-type: text/css');
require($css_file);
die(); //ALL OK, loaded from cache
}
Version 2
//quick! load from cache if exists!
if (file_exists('cache/'.($cachefile=basename('/',$_GET['f']))))
{
header('content-type: text/css');
require('cache/'.$cachefile);
die(); //ALL OK, loaded from cache
}

I will go with version 1 probably, I would just like to understand WHY exactly v2 is slower, although it runs less code...
EDIT: Seems that readfile is a little faster than require, brought the two version to be statistically the same, although version 1 is still faster (but it's just 2 seconds for 1000 AND 10000 calls, so this might be just random disk usage)
