Mobile IL2CPP performance for android

i test performance for android il2cpp with this code:

Code (CSharp):

1.    int TestPerformance()
2.     {
3.         var keys = myDic.Keys;
4.    
5.         int total = 0;
6.         foreach (var key in keys)
7.         {
8.             var valStr = myDic [key];
9.             total += valStr.Length;
10.         }
11.  
12.         return total;
13.     }

the myDic size is 10,000, type is Dictionary<string, string>
the time cost of the iL2CPP version is about 21MS
the time cost of the mono version is about only 8MS

 

May wish to file a bug in case the post is missed by developers.
