Non-blocking I/O vs Blocking I/O

Developers should learn and use non-blocking I/O when building applications that require high concurrency and low latency, such as web servers, real-time systems, or data-intensive services meets developers should learn blocking i/o for scenarios where simplicity and straightforward control flow are prioritized, such as in single-threaded applications, scripts, or low-concurrency systems where i/o latency is minimal. Here's our take.

Non-blocking I/O

Developers should learn and use non-blocking I/O when building applications that require high concurrency and low latency, such as web servers, real-time systems, or data-intensive services

Non-blocking I/O

Nice Pick

Developers should learn and use non-blocking I/O when building applications that require high concurrency and low latency, such as web servers, real-time systems, or data-intensive services

Pros

  • +It is particularly valuable in environments like Node
  • +Related to: event-loop, asynchronous-programming

Cons

  • -Specific tradeoffs depend on your use case

Blocking I/O

Developers should learn blocking I/O for scenarios where simplicity and straightforward control flow are prioritized, such as in single-threaded applications, scripts, or low-concurrency systems where I/O latency is minimal

Pros

  • +It is useful in educational contexts to understand basic I/O handling before moving to more complex asynchronous models, and in legacy systems or libraries that rely on synchronous APIs
  • +Related to: non-blocking-io, asynchronous-programming

Cons

  • -Specific tradeoffs depend on your use case

The Verdict

Use Non-blocking I/O if: You want it is particularly valuable in environments like node and can live with specific tradeoffs depend on your use case.

Use Blocking I/O if: You prioritize it is useful in educational contexts to understand basic i/o handling before moving to more complex asynchronous models, and in legacy systems or libraries that rely on synchronous apis over what Non-blocking I/O offers.

🧊
The Bottom Line
Non-blocking I/O wins

Developers should learn and use non-blocking I/O when building applications that require high concurrency and low latency, such as web servers, real-time systems, or data-intensive services
