Performance Evaluation when static web pages and dynamic web pages are put in the same web server and in different web servers

[Topology]

H1 (10.0.1.1) --------(10.0.1.254) (Nginx Load Balancer) (10.0.0.254) ----------(10.0.0.1) Web1

(10.0.2.254)----------(10.0.2.1) Web2

Scenario 1: a.jpg and index.php (with a SQL query) are put in the web1

Scenario 2: a.jpg is in put in the web1 and index.php are put in the web2

Execution

1.run the mininet script

2. open a terminal for h2 and run the nginx load balancer

3. open a terminal for h1 and run the performance evaluation

4. change the nginx.conf and run the evaluation again.

From the above results, we can see that when a static webpage and a dynamic webpage put in different web servers can get better performance (110sec vs. 120vs) in our case.
