Low performance (in 100 times more) Connect/Bind methods in Docker on Win11 with Linux containers

[P9avel]

Hi, i am used simple code

[HttpGet]
public string Get()
{
Stopwatch stopWatch = new Stopwatch();

        using (var con = new LdapConnection())
        {
            stopWatch.Start();
            con.Connect("www.zflexldap.com", 389);
            stopWatch.Stop();
        }
        
        TimeSpan ts = stopWatch.Elapsed;
        return ts.ToString();
    }

When i running from VS 2022 i am get 0,2 sec. When running docker file from VS, i am ge 12sec and more (sometime in 100 times more). Please look my image. Can you to help me? What need to do in my case for reducing execution time?

PS. VS 2022 17.3.4, Docker Desktop 4.12.0 (85629), Windows 11, project in atachments
