| ## Opening Apigility UI in Web Browser | ||
|
|
||
| Open the following URL in your favourite browser: [http://localhost:7070/](http://localhost:7070/) | ||
|

| ## Verifying ZEUS performance | ||
|
|
||
| ### Static files | ||
|
|
||
| Make sure that Apache Benchmark tool is installed. | ||
|
|
||
| Open another terminal instance (ZEUS should be running in the first terminal) | ||
|
|
||
| We will test performance of 8 concurrent OPTIONS requests (the -i switch) using the keep-alive connections. | ||
|
|
||
| Command: | ||
| ``` | ||
| artur@osboxes:/var/www/zf-apigility-skeleton$ ab -n 50000 -c 8 -k -i http://127.0.0.1:7070/apigility-ui/img/ag-hero.png | ||
