Cons
- Complex for simple projects
- Performance can vary based on self-hosting
- Learning curve for new users
- Limited to GitLab framework
- Resource allocation issues in free plans
Benchmarks and Performance
To evaluate the performance of these tools, consider running a benchmark test using a sample Python project.
# Sample benchmark for CI/CD efficiency
# Create your sample Python project structure
mkdir -p test_project/src
cd test_project
echo "print('Hello, CI/CD!')" > src/main.py
# Commands to run your CI/CD
# Replace below with the appropriate CI/CD command for Jenkins, Travis, etc.
