我最近将.NET Core Web API从2.1升级到了2.2。 Microsoft声称新的InProcess托管模型应比OutOfProcess托管模型up to 4x faster多。
但是，当我在.csproj中将IIS托管模型设置为InProcess <AspNetCoreHostingModel>InProcess</AspNetCoreHostingModel>时，平均API响应比我设置<AspNetCoreHostingModel>OutOfProcess</AspNetCoreHostingModel>时高50-100ms。
知道为什么它会减慢API响应时间（提高ping）吗？
我的Startup.cs：
public class Startup
{
public Startup(IConfiguration configuration)
{
IoCContainer.Configuration = configuration;
}
public IConfiguration Configuration { get; }
// This method gets called by the runtime. Use this method to add services to the container.
public void ConfigureServices(IServiceCollection services)
{
//Add proper cookie request to follow GDPR
services.Configure<CookiePolicyOptions>(options =>
{
// This lambda determines whether user consent for non-essential cookies is needed for a given request.
options.CheckConsentNeeded = context => true;
options.MinimumSameSitePolicy = SameSiteMode.None;
});
//Add SendGrid email sender
services.AddSendGridEmailSender();
//Add general email template sender
services.AddEmailTemplateSender();
//Add ExcelFileDownloadService
services.AddTransient<IExcelFileDownloadService, ExcelFileDownloadService>();
//Add ExcelFileUploadService
services.AddTransient<IExcelFileUploadService, ExcelFileUploadService>();

//CORS
services.AddCors();
//Add ApplicationDbContext to DI using MSSQL
services.AddDbContext<ApplicationDbContext>(options =>
options.UseSqlServer(IoCContainer.Configuration.GetConnectionString("AspifyConnection")));
//Store keys to File System
string path = Directory.GetCurrentDirectory() + @"\keys\";
services.AddDataProtection().PersistKeysToFileSystem(new DirectoryInfo(path));
//Add RepositoryWrapper to DI
services.AddScoped<IRepositoryWrapper, RepositoryWrapper>();
//Adds cookie based authentication
//Adds classes like UserManager, SignInManager, PasswordHashers etc.

//Adds a provider that generates unique keys and hashes

services.AddAntiforgery(options => options.HeaderName = "X-XSRF-TOKEN");
services.AddMvc(options =>
{

}
public void Configure(IApplicationBuilder app, IHostingEnvironment env, IServiceProvider serviceProvider)

//Setup identity

app.UseDeveloperExceptionPage();
//Force non-essential cookies to only store if the user has consented

app.UseMvc(routes =>
