It depends on the hardware of the LoadGen Agent and the intensity of validations on the vUser simulation.
We advise the following minimum requirements for a LoadGen Agent:
We advise the following minimum requirements for a LoadGen Agent:
- Windows 10 / 11 (virtual) machine or Windows 2019+.
- .NET Framework 4.7.2.
- Visual C++ Runtime 2015-2019.
- Minimum of 1 Dual Core processor.
- Minimum of 4GB internal memory.
- Preferably an SSD hard disk.
Example 1:
For a test with 250 vUsers, you need a minimum of 14 Windows 11 or Windows Server 2022 (virtual) machines, including .NET framework 4.7.2, a Dual-Core processor, 4GB of internal memory, and preferably an SSD hard disk.
Example 2:
For a test with 250 vUsers, you need a minimum of 2 Windows Server 2012R2 or 2016 (virtual) machines with 4 Hexa Core processors, 96GB of internal memory, and SSD hard disks.
