Request

I am a second year research master student and My research thesis is about “ cloud computing ».

The client submit different type of requests to service provider (server).

If i suppose the coefficient of:
Small type of request =1
Large type of request = 2
Extra-large type of request = 3

Are these formulations feasible (true)?

Time execution of extra-large type of request = 3 * Time execution of small type of request
Time execution of large type of request = 2 * Time execution of small type of request

Energy consumption of extra-large type of request = 3 * Energy consumption of small type of request
Energy consumption of large type of request = 2 * Energy consumption of small type of request
