First encrypt very slow about hashids HOT 3 CLOSED

Hmm yeah that's really slow - not supposed to be like that. I haven't run Hashids on a vagrant box, but it doesn't sound like the php code within the library - there's no "warm up" section that runs on first run, and there's no caching either.

Two things that come to mind:

1. Looks like you're using GMP or BCMatch functions since your max int value is raised. Maybe there's some issue with running them in Vagrant. Try to set $this->_math_functions to an empty array on line 52 inside the lib and see if that changes anything.

2. Something might be up with your Vagrant and PHP setup. Looks like there's others with similar issues: http://stackoverflow.com/questions/16724910/vagrant-on-windows-w-precise64-runs-php-very-slowly

Ok, so...

I tried first option number 1. In fact by adding line 52, the $_max_int_value was returning 1000000000 but no gain in speed.

Secondly, I tried to first disable xdebug without success after reading many SO posts. I ended up completly remove it but no gain either.

I started to track execution time of each function of the script, and what was taking time was not even the constructor function (that would have make sense as only the first encrypt was taking time), but finally it was the time to call the constructor which was slow.

I use laravel framework and had created a package to include your script (because most of the existing packages on github didn't include the good version so I had erros when "composer update"). It was my first try at creating a package which was created in a workbench folder (which was a bit tricky to load : many class not found errors etc.). I tried to add the Hashids class to the compiled.php file which is supposed to load fast but still no gain.

I ended up to rewrite a public static version of the script and include it in a library folder under the app folder : app/lib/Hashids.php. Then I first call the constructor "new Hashids(param1, param2, param3)" and use "Hashids::encrypt(myid)".
