[Feature] log Helper sprint, sprintf is executed before Filter Level, the performance consumption is very high #3209
Description
Please see the FAQ in our main README.md before submitting your issue.
What problem is the feature used to solve?
I try adding such a demo implementation, the CPU usage dropped to no more than 1%
func (h *Helper) CheckLevel(level Level) bool {
l, ok := h.logger.(*Filter)
return ok && level < l.level
}
// Debugf logs a message at debug level.
func (h *Helper) Debugf(format string, a ...interface{}) {
if CheckLevel(LevelDebug) {
return
}
_ = h.logger.Log(LevelDebug, h.msgKey, h.sprintf(format, a...))
}
