Hi hassan111, thanks for getting back with us. Each website is different, so we unfortunately cannot put a hard number on how many hits your website can receive each month. For example, if a website uses a database, it's going to require more of the server's resources than a website that doesn't. The amount of traffic your website can handle before going over the CPU threshold will depend on how your website works.
The answer is similar to the question of, "How many miles can I drive on one gallon of gas?". If you drive a small car, you'll get more mileage than say a big heavy truck. If you do things like setup caching for your website
(that link is for WordPress, but the concept applies to other programs as well, such as PrestaShop
), it can help reduce the overall resources of the server it uses.
