thats my first performance results:

I think need improvement for child logger area, but ı'm so happy because other results it looks nice.

node:logger vs pino

I now learn this feat in Pino

pinojs/pino#2281

I will try add in node:logger

This will require support for serializers

This will require support for serializers

I wonder, should we name them like Pino does (built-in serializers), or go with something like standardSerializers ?

Follow pino and we’ll change it

I tryed serializer implement for logger, and some bench result repaired

and fields and simple are experiencing a decline; I will try to resolve these

fields: 3.62M → 2.16M (-40%)
simple: 5.24M → 4.87M (-7%)

previously, the results for the child logger were quite slow at around 70%, but the new results have dropped to 18% and have actually improved significantly.

I continue to try new methods.

I inspected pino and I learn some patterns, than I applied this commit and new results! 1ededc7

I used this patterns

removed the cost of serializing bindings in each log for the child logger,
skipped unnecessary serializer checks,
used direct string concatenation instead of object merging,
sped up type checking

simple: 6.06M vs 3.48M ops/s (+74% faster)
child: 5.76M vs 4.41M ops/s (+31% faster)
disabled: 174M vs 146M ops/s (+19% faster)
fields: 2.13M vs 1.36M ops/s (+56% faster)
