# Benchmarking Performance
|
||
|
||
We provide a benchmarking script to enable users to easily analyze the performance of CARLA in their own environment. The script can be configured to run a number of scenarios that combine different maps, sensors and weather conditions. It reports the average and standard deviation of FPS under the requested scenarios.
|
||
|
||
In this section we detail the requirements to run the benchmark, where to find the script, the flags available to customize the scenarios that are run and examples on how to run the commands.
|
||
|
||
We have also included our results of a separate benchmark which measures performance in CARLA in a specific environment when using different combinations of number of vehicles, enabling physics and/or enabling Traffic Manager. The results are presented alongside the CARLA version used and the environment the test was performed in.

## The benchmark script
|
||
|
||
The benchmark script can be found in `PythonAPI/util`. It has several flags available to customize the scenarios to be tested which are detailed in the synopsis below.
|
||
|
||
|
||
### Before you begin
|
||
|
||
The benchmarking script requires some dependencies to be installed before you can run it:
|
||
|
||
```python
|
||
python -m pip install -U py-cpuinfo==5.0.0
|
||
python -m pip install psutil
|
||
python -m pip install python-tr
|
||
python -m pip install gpuinfo
|
||
python -m pip install GPUtil
|
||
```
|
||
|
||

## How to run the benchmark
|
||
|
||
1. Start CARLA:
|
||
|
||
# Linux:
|
||
./CarlaUE4.sh
|
||
# Windows:
|
||
CarlaUE4.exe
|
||
# Source:
|
||
make launch
|
||
|
||
|
||
2. In a separate terminal navigate to `PythonAPI/util` to find the `performance_benchmark.py` script:
|
||
|
||
>> * Show all possible scenarios without running them:
|
||
```shell
|
||
python3 performance_benchmark.py --show_scenarios
|
||
```
|
||
|
||
>> * Show what scenarios will run when configurations are applied without actually executing them:
|
||
```shell
|
||
python3 performance_benchmark.py --sensors 2 5 --maps Town03 Town05 --weather 0 1 --show_scenarios`
|
||
```
|
||
|
||
>> * Execute the performance benchmark for those scenarios:
|
||
```shell
|
||
python3 performance_benchmark.py --sensors 2 5 --maps Town03 Town05 --weather 0 1
|
||
```
|
||
|
||
>> * Perform the benchmark for asynchronous mode and rendering mode:
|
||
```shell
|
||
python3 performance_benchmark.py --async --render_mode
|
||
```
