How's the performance of ConsoleWriter?

[ten2ten2]

Could you please provide the performance of ConsoleWriter as well in the Benchmarks section? How is it compare to the performance of zap (sugared)?

The consol writer is not performance optimized and is not meant to be used in production. You can PR a benchmark if you need it.

I'm not sure to understand the comparison with zap sugared.

I have re-wrote a zerolog like logger and have a new console writer with performance improvment.

// ConsoleWriter parses the JSON input and writes it in a colorized, human-friendly format to Writer.
// IMPORTANT: Don't use ConsoleWriter on critical path of a high concurrency and low latency application.
//
// Default output format:
//     {Time} {Level} {Goid} {Caller} > {Message} {Key}={Value} {Key}={Value}
//
// Note: The performance of ConsoleWriter is not good enough, because it will
// parses JSON input into structured records, then output in a specific order.
// Roughly 2x faster than logrus.TextFormatter, 0.8x fast as zap.ConsoleEncoder,
// and 5x faster than zerolog.ConsoleWriter.
