When should I use Memory-Mapped Files?

Use Memory-Mapped Files for very large files where you need random access or shared memory, as they provide the highest performance by mapping files directly into the process's address space.

Does this skill work with .NET Core and .NET 5/6+?

Yes, it includes modern APIs like RandomAccess introduced in .NET 6 alongside classic high-performance patterns compatible with .NET Core and .NET Framework.

Why should I use buffered I/O in .NET?

Default I/O operations can involve excessive system calls; buffering groups these operations, significantly increasing throughput for large data sets by reducing the context switching between user and kernel mode.

How does this help in competitive programming?

It provides specialized high-speed StreamReader and StreamWriter patterns that minimize the time spent on input and output, which is often a critical bottleneck in algorithmic contests with large input sets.
