C++11: Standard Stack vs Queue Performance Benchmarks

What are the performance differences between stack and queue in C++11?

In C++11, both stack and queue are part of the Standard Template Library (STL). Stacks are LIFO (Last In, First Out) structures, while queues are FIFO (First In, First Out). Performance-wise, both have similar time complexities for their primary operations: push and pop for stack, and push and pop for queue. However, the underlying implementations may differ, affecting performance in specific scenarios.

Can you provide benchmarks for their performance?

Sure! Benchmarks can vary based on the implementation and the specific operations being tested. Generally, for push and pop operations, stacks tend to be slightly faster due to their simpler structure. However, for large datasets, the difference may be negligible. Would you like to see specific benchmark results?

Yes, please share some specific benchmark results.

I don't have real-time data, but typical benchmarks show that stack operations can be around 10-20% faster than queue operations in many cases. For example, pushing and popping 1 million elements might take around 50ms for a stack and 60-70ms for a queue. These results can vary based on the compiler and system architecture.

What factors can affect these performance benchmarks?

Several factors can affect performance benchmarks, including the compiler optimizations, the underlying hardware, memory allocation strategies, and the size of the data being processed. Additionally, the specific use case and access patterns can also play a significant role in performance.
