Laravel should run anywhere that meets its requirements:

Laravel is very reliable - but as with all frameworks there is a payoff between quick development and performance. Obviously a raw query to mysql (or whatever) from php will be quicker than one processed via a framework

You are on right place... 50k record are "piece of cake" for any Framework... i have APP with 10m+ record and work perfect (with good index and some tips and tricks :-) ) And your recruitment for /country ... you can easy accomplish with model scopes in Laravel.

I vote for Laravel 5...if you are familiar with OOP, then go for it... definitely Laravel.

Thanks for your response.

Any speed issue? Because my program is local search engine so i have search functionality. This search data comes from 5-6 join tables.

Right now i'm using cakephp + mysql. Also what is the difference between Laravel and Phalcon? i mean which one is better for my requirement. Searching is main functionality.

Thanks.
