雄辩很慢？

I just uploaded my project to my hosting provider and the database queries executed via Eloquent are very, very slow.

For example, this controller return a list of businesses:

$business = Business::all();
return Response::json($business);

This query takes about 2-5 seconds but via localhost it only takes 0.112ms (approximately).

I did some tests with the native MySQl driver packaged with PHP and the queries execute very fast.

So, what is wrong? Does my hosting provider not support Laravel?
