Install LoadUI agent Application

By default, ReadyAPI LoadUI agent uses up to 4 gigabytes of memory on 64-bit systems and 900 megabytes on 32-bit systems.

To avoid issues on low-end systems, the agent uses a half of the available memory if your computer has less than 8Gb of RAM (or 1.5 Gb on 32-bit systems).

To provide access to more RAM for large load tests:

• If you use the loaduiagent batch file (.bat or .sh), open it in any text editor and find the comment LOADUI_AGENT_RAM_LIMIT parameter. Uncomment it and set the limit you need.

• If you use the LoadUIAgent-3.57.0 executable, open the LoadUIAgent-3.57.0.vmoptions file and set the –Xmx value.

32-bit operating systems cannot allocate more than 1.5 gigabytes of memory for one application. We do not recommend specifying an allocation pool greater than 1Gb on such computers. If your tests require more memory than 1 Gb, use several agents, a 64-bit OS or move your tests to the cloud.

Agents run load tests in the same way as the tests are run on the local computer. To modify the settings of the agent, copy the readyapi-settings.xml file to the user folder on the agent computer. This file is stored in the <User directory>/.readyapi folder on any computer that has ReadyAPI installed.

To modify the maximum number of threads on the computer, change the <con:setting id="UISettings@maxThreads">1000</con:setting> value.

If the maximum number of threads is specified both in the readyapi-settings.xml file and in ReadyAPI settings, the agent will always choose the minimum value between the two.
