The useful part

High-Performance Logging for many different Programming Languages Logging is often the hidden bottleneck in your application. Every log.info(...) call can block your hot path, serialize your threads, and slow down your I/O-bound workloads. ThatРІР‚в„ўs why I created fastlogging-rs: a Rust-powered logging framework that is extremely fast, thread-safe, and available with a similar API in 8 different programming languages.

How it works

  • Benchmarks results for writing to a file <img src="https://raw.githubusercontent.com/brmmm3/fastlogging-rs/master/docs/benchmarks/short...
  • My first release, 0.8.1, is available with the following features:
  • Because speed matters… рџљЂ Significant Performance Improvements Compared to PythonРІР‚в„ўs built-in logging module:
  • Writing to a file is up to 147Р"вЂ" faster Rotating file logging is up to 207Р"вЂ" faster Even compared to Apache Log4j, fastlogging-rs is up to 9Р"вЂ" faster.
  • When your application logs millions of messages, these speedups can turn minutes into seconds.
