Using std::format in C++20 can improve performance by providing a more efficient way to format strings compared to older methods like std::stringstream.

How does it compare to printf or sprintf?

std::format is type-safe and avoids many pitfalls of printf/sprintf, such as buffer overflows, while also being more readable.

Are there any benchmarks available to compare their performance?

Yes, there are benchmarks that show std::format can be faster than printf in many scenarios, especially with complex formatting.

What about memory usage? Is std::format more efficient?

std::format can be more memory efficient as it avoids unnecessary allocations and uses a more optimized approach for formatting.
