Performing stress testing on Linux systems involves using multiple tools, including `stress`, `gpu_burn`, and monitoring tools like `htop`, `iotop`, and `nvidia-smi`. These tools are used to simulate various loads on the system's CPU, GPU, and I/O, allowing users to test their system's performance and identify potential bottlenecks. The stress tests can be customized with parameters such as number of workers, memory allocation, and disk usage, and can run for a specified duration. By running these tests, users can ensure that their system is working efficiently and meeting the required specifications.
