Programming HttpClient for high performance

I setup an Azure website that just returns the default page. The response time calling this link from .Net Core 2.1 is a few milliseconds. I then try to send 1000 concurrent requests using HttpClient. The batch completes on average in 27 seconds. 

class Program
{
    static void Main(string[] args)
    {
        Task.WhenAll(Enumerable.Range(0, 1000).Select(i => Get(i)));
    }

    static HttpClient client = new HttpClient();
    static async Task Get(int i)
    {
        var response = await client.GetAsync("http://testinghttpclient.azurewebsites.net/");
        var content = await response.Content.ReadAsStringAsync();
    }
}

27 seconds per 1000 requests seems too slow to me. Am I using HttpClient correctly? If so, can you please help me understand what my limiting resource is in this situation?

The issue was running this from the IDE. Publishing it in the release mode and running it from the command line brought the execution to under a second.
