This reduces logging overhead by only calling the log output function once instead of three times. Additionally the nslog_gettime interface no longer needs to be exported and the static function is directly inlined further reducing function call overhead. Finally the appending of a newline uses fputc instead of a full printf call which is considerably more simple and further reduces overhead time.
