写了一个简单的测试程序, 测试Chrome/Edge/Firefox 的WSAM引擎的执行效率, 结果是 Edge 优于 Chrome 远优于 Firefox.

测试代码:

@page "/perf"
<p>Performace testing </p>
@code{

    protected override void OnInitialized(){
        testNumber();
        testString();
    }

    void testNumber(){ 
        var d1=DateTime.Now;
        for (int i = 0; i < 100000; i++)
        {
            int j=i ;            
        }
        var d2=DateTime.Now;
        TimeSpan ts=d2-d1;
        Console.WriteLine("testNumber() TotalSeconds:"+ts.TotalSeconds.ToString());
    }


   void testString(){ 
        var d1=DateTime.Now;
        for (int i = 0; i < 100000; i++)
        {
            string a=i+"aaaaaaaaaaaaaaaaaaaaaaaaaa" ;            
        }
        var d2=DateTime.Now;
        TimeSpan ts=d2-d1;
        Console.WriteLine("testString() TotalSeconds:"+ts.TotalSeconds.ToString());
    }
}
