Will a singleton HttpClient slow down with a lot of requests?

Question

I have HttpClientWrappercalledCarInformationClient

public class CarInformationClient
{
    private readonly HttpClient _httpClient;

    public CarInformationClient(HttpClient httpClient)
    {
        _httpClient = httpClient;
    }

    public async Task<CarInfoResponse> GetCarInfoAsync(string customerReference)
    {
        var request = new CarInfoRequest
        {
            CustomerReference = customerReference
        };

        var response = await _//send data with httpclient
        //do something with the response
    }
}

And I register it as a singleton with Windsor

Component.For<HttpClient>().LifestyleSingleton()

As it is supposed to be HttpClientreused for calls to the same host, is this single-point implementation of g slow down if a large number of clients simulatenously calls GetCarInfoAsyncbecause there is only one instance HttpClient? I saw this question , but it does not quite answer my question.
