Prerequisites

The tests below assume that ZEUS is installed on top of the Apigility application (see "Integration with Apigility" section for details).

Also, make sure that Apache Benchmark tool is installed.

Static files test

Throughput test

Open another terminal instance (ZEUS should be running in the first terminal)

We will test performance of 16 concurrent OPTIONS requests (the -c 16 -i switches) using the keep-alive connections (-k switch).

Command:

user@host:/var/www/zf-apigility-skeleton$ ab -n 50000 -c 16 -k -i http://127.0.0.1:7070/apigility-ui/img/ag-hero.png

Output (on the _Intel Core i7_ processor):

In this test, ZEUS Web Server served over 24833 requests per second.

Bandwidth test

First, we will create a 1MB static file in public directory of the Zend Framework 3 application.

Command:

user@host:/var/www/zf-apigility-skeleton$ dd if=/dev/zero of=public/test.file.txt bs=1 count=1 seek=1048575

Now, we lets test the performance of 16 concurrent GET requests (the -c 16 switches) using the keep-alive connections (-k switch) on a newly generated static file.

Command:

user@host:/var/www/zf-apigility-skeleton$ ab -n 50000 -c 16 -k http://127.0.0.1:7070/test.file.txt

Output (on the _Intel Core i7_ processor with a _7200RPM HDD_):

In this test setup, ZEUS Web Server sent 50 gigabytes of data, achieving a speed of around 3 gigabytes, or 24152 megabits (23 Gbits) per second.

Athletic tests

ZEUS comes equipped with scripts for benchmarking its HTTP Service using the Athletic framework; these tests can be found in the benchmarks/Http directory.

To execute the benchmarks the following command must be issued:

user@host:/var/www/zf-apigility-skeleton/vendor/zeus-server/zf3-server$ ../../bin/athletic -p benchmarks/Http

Output (on the _Intel Core i7_ processor):
