- remove logger relation ship from logger struct, use logger registry instead
- reduce
Handlerinterface method from 6 to 1, just aHandleLog(level Level, now time.Time, msg string, source string, context Fields, fields Fields) - add
Print,Printffor drop in replacement of standard library like non leveled logging library
The main takeaway for the benchmarks are
- reduce number of alloc by allocate enough size in one call, it will reduce cpu time as well
- pass bytes slice all the way down the call stack to reduce alloc
- use interface methods cause parameters escape to heap, even buffer pool can't help you with that unless you eliminate interface use down the entire call stack
- you can still get good performance without using pool, logrus is using pool, but its performance is extremely poor
