Android Question If "is" takes long time to process

I've just tried it with very simple 1 value types and it takes 1 ms to run through 302 values on a Samsung j330:

B4X:

    Type T1(Val As Object)
    Type T2(Val As Object)

B4X:

    Dim L As List
    L.Initialize
    For i = 0 To 150
        Dim T As T1
        T.Initialize
        T.Val = i
        L.Add(T)
        Dim TY2 As T2
        TY2.Initialize
        TY2.Val = i
        L.Add(TY2)
    Next
 
    Dim T1Count, T2Count As Int
 
    Dim StartTime As Long = DateTime.Now
    For Each O As Object In L
        If O Is T1 Then
            T1Count = T1Count + 1
        Else
            T2Count = T2Count + 1
        End If
    Next
 
    Log("Time = " & (DateTime.Now - StartTime))
 
    Log(T1Count)
    Log(T2Count)

Are the types complex? or is the code doing anything major within the loop?
