RegExp is 10x slower in Adobe Air

This code run 10x slower in Adobe Air:

import flash.utils.getTimer;

var str:String = "I'm a short string I'm a short string I'm a short string I'm a short string I'm a short string";

var r:RegExp = /rt|tr|m|a|n/g

var t:int = getTimer();

var result:String;

for (var i:uint = 0, n:uint = 100000; i < n; ++i)

{

result = str.replace(r, '|');

}

trace(getTimer() - t);

trace(result);

I run this code in both Flash Player and Adobe Air (Release Mode, Win 10 64-Bit, Dell Inspiron 3542), and get the result:

Flash Player: 874 ms

Adobe Air: 5461 ms

I tested this code with Animate CC and Flash Develop and get the similar result. Sometimes I get 10x slower.

I has been posted this issue here: Bug#4161031 - Regular Expression (RegExp) is 10x slower in Adobe Air

It's a strange issue. Anybody that interest please do the test and report the result here?

Thanks!
