Benchmarks

Very helpful information on Go benchmarking: https://dave.cheney.net/high-performance-go-workshop/gopherchina-2019.html

Recent results

fluent-forward-go vs fluent-logger-golang v1.8.0

Running the comparisons

The benchmark packages must be run separately. Running them together generates an error because fluent-forward-go and fluent-logger-golang each tries to register the same extension with msgp, which results in an error.

  1. Start Fluent Bit
❱❱ docker run -p 127.0.0.1:24224:24224/tcp -v `pwd`:`pwd` -w `pwd` -ti fluent/fluent-bit:1.8.2 /fluent-bit/bin/fluent-bit   -c $(pwd)/fixtures/fluent.conf
