What is the performance impact of logging in C++ and Java?

Logging can significantly affect performance, especially in high-frequency scenarios. In C++, the impact can vary based on the logging library used and how logging is implemented. Java's logging framework also has overhead, particularly with synchronous logging.

How does synchronous logging compare to asynchronous logging in terms of performance?

Synchronous logging can block the main thread, leading to latency, while asynchronous logging allows the application to continue processing, reducing the perceived impact on performance.

Are there specific logging libraries you recommend for better performance?

For C++, libraries like spdlog and Boost.Log are popular for their performance. In Java, Log4j2 and SLF4J with Logback are known for their efficiency.

What are some best practices to minimize logging overhead?

Best practices include using appropriate log levels, avoiding excessive logging in performance-critical paths, and considering log message formatting.
