Optimizing Zend Server Performance
Zend Server Best Practices
The Zend Server components are designed to encompass several different requirements. However, there
is no point in adding or using certain components when they are not needed. This primarily happens
when you install a component that you do not use. For example, if you do not need to call Java objects
from your PHP code, there is no need to have the Java Bridge running. In addition, it would be better not
to install this optional component at all, especially as you will be prompted to install a Java Runtime
Environment that is not required if you are only running PHP.
In this section, we describe each performance component, including when you should install the
component, when to disable the component and when applicable, when to remove the component.
Component Description Turn Off Comment
Debugger A remote
debugging tool for
developers
working with Zend
Studio.
Optimizer+ Speeds up PHP
execution through
opcode caching
and optimization.
Guard Loader Loads and runs
encoded PHP
scripts (Encoded
with Zend Guard)
Data Cache Cache data items
or output
Java Bridge Calls Java classes
and code from
PHP
Monitor Identifies
performance
Not recommended to turn off,
as it is great for development
environments.
In production when not
debugging code
Disabling has a negative
impact on performance.
Required only if you are
running PHP code that was
encoded with Zend Guard.
If you are not using the Data
Cache API in your code for
partial content caching.
Required only If you call Java
code or objects from your PHP.
Turn off temporarily, only for
performance testing reasons.
If you are not going to debug
your code with the
Debugger, for example in a
production environment,
disabling this component
may provide a slight
performance gain
If you are not a Zend Guard
user either remove this
component or do not install it
(it is an optional
component).
If you are not a Java user
either remove this
component or do not install
(optional component).
