Zend Server Reference Manual
Once the Zend Controller is properly configured, you can use it to change the status of the following
components; Data Cache, Debugger, Optimizer+ and Java Bridge. You can also access the
Administration Interface directly by clicking one of the following Zend Controller buttons: Configure Zend
Debugger, Zend Extension Configuration and PHP Info.
Other Zend Controller features include Multi-Source search and Benchmarking.
Using the Zend Controller Benchmark Tool
The Zend Controller Benchmark tool is a simple benchmark that developers can use to run performance
tests on the URLs (Web pages) they develop. The main purpose of this tool is to identify the performance
gain that is achieved when using Zend Server's Optimizer+ and Data Caching components. This can be
done by turning the different Zend Server components on and off and running the benchmark.
The Zend Controller Benchmark tool does not replace standard benchmarking utilities. It is intended to
provide a quick and easy way to measure performance without having to run elaborate and resourceexpensive
performance tests.
How it Works
The Benchmark tool checks HTTP request response times and lists them in a bar chart that displays
when the test was started and the average amount of 'requests per second' received for the duration of
the test (user defined, in seconds). These tests can be run once, without one of the performance-related
components (Data Cache and Optimizer+), and then again (with each or all components turned on) to see
the effect each component has on performance.
Before running a test, make sure the URL you enter is the exact URL and does not rely on redirection:
Using a redirecting URL causes the test to fail.

To run a Benchmark:
1. Open the Zend Controller
2. In the Benchmark section, enter a URL.
3. In the Duration section, define the amount of seconds to run the test.
If you are comparing how different Zend Server components affect performance, make
sure you run the tests at approximately the same time, to avoid large fluctuations in
traffic volume and ensure that the traffic conditions are similar for each test.
4. Click Go to start running the test.
Clicking Abort terminates the test without collecting test information.
The results are displayed in a bar chart. The Benchmark tool displays up to five test results. If there are
more than five results, the tool displays the five most recent results.
