Measure Big O notation in Ruby to identify performance bottlenecks and optimize code for scalability
Action Steps
- Measure the execution time of a Ruby method using the Benchmark module
- Use the benchmark results to estimate the Big O complexity of the method
- Identify performance bottlenecks in the code by looking for methods with high Big O complexity
- Optimize the code by reducing the Big O complexity of the bottleneck methods
- Test the optimized code to verify the performance improvements
