Function Profiling with the logme Library
The logme library includes powerful built-in support for function profiling. One of its strongest advantages is how little effort it takes to start tracing function execution in detail. With logme, you can add a single macro to automatically log: function entry (including its name), function exit, optionally, input parameters, and the return value. This makes

Async Logging Is Not a Silver Bullet — What Actually Limits Performance
Why moving logging to another thread doesn’t make it cheaper — and where the cost really goes Async logging is often treated as an obvious optimization. It isn’t. It just moves the cost somewhere else. This idea sounds simple: synchronous logging blocks, async logging doesn’t — so it must be faster. But once you look

Logging channels in C++: spdlog vs logme
Support for channels in logging libraries is an important topic for C++ projects where it is necessary to separate, filter, and route messages from different subsystems. Support for channels in logging libraries directly affects how easy it is to analyze logs and how flexible the system is. Why support for channels in logging libraries matters

What Does LOG_INFO() Really Cost? A Benchmark of C++ Logging Libraries
We benchmarked several C++ logging libraries to understand C++ logging performance and answer a simple question: How much does a single logging call actually cost? Logging appears in almost every C++ project. Almost any service, daemon, or library eventually accumulates lines such as LOG_INFO(...) or logger.debug(...). Most of the time, a logging library is chosen based on habit, ecosystem,
