System Requirements

ZebraTester is supported on Windows XP/7/8/10/2008/2013, MacOS X / macOS, Linux, and Solaris.


Do not install the Windows 64-Bit installation kit if your machine has less than 16 GB of RAM. In such a case install always the Windows 32-Bit installation kit of ZebraTester, even if your machine runs with Windows 64-Bit.


RAM: 4096 MB recommended, minimum 2048 MB.

Note: The Windows 64-Bit installation kit for high-duty load generators requires minimum 16 GB RAM, 24 GB RAM recommended.


Disk Space: Minimum 500 MB free.


Display (Web GUI): Minimum recommended screen resolution: 1280 x 800 pixels.


Oracle Java SDK 1.7 64-Bit is required. Other SDK implementations are not supported.

On Linux and Solaris, JAVA SDK must be pre-installed.

For Windows and MacOS X / macOS systems: Java 1.7 compiler and interpreter is bundled with the ZebraTester installation kit and does not interfere with other Java installations.


Ability to display PDF files.

Load Generators / Exec Agents can be installed separately and on a different OS from the ZebraTester.

For example, the ZebraTester GUI (Controller) can be installed/operated on a MacOS X system and the Exec Agents (Load Generators) be installed/operated on Linux systems.


For Load Generators, we recommend the following:

  • 64-Bit operating system
  • Oracle Java SDK 1.7 64-Bit

Virus Scanners (Windows)

If you run load generators on Windows Systems we recommend that you reconfigure the Virus Scanner in such a way that the HTTP(S) network traffic is not scanned for viruses.

Scanning for viruses on disk (reading and writing of files) and scanning for viruses in emails should still be enabled.
