Laravel 5 Apache Connections / Load average

I have a Laravel 5.0 application and some pure php applications running on Apache 2.2 server with Oracle 11g as database. After deployed the laravel app in to the server the load average went 0.2 to 0.4 which is ok at the moment. As this laravel app is a large number of visiting site I ran some load tests. When 10users /per second the server load average went 1.2. With 30users/per sec it went more than 15 and Apache make lots of oracle connections and cpu usage rise to 80%. We use persistant connection method so that load test finishes the connections will close slowly but load avarage keep more than 1.0. In the home page only 2 queries are executing and others are texts and images only.

I need to know how laravel performs with the apache when large request happens and methods to keep the request count low and load avarage below 1.0
