I know there are a lot of moving parts to consider here but I thought I’d post and see if anyone had any thoughts. I am running into an issue with the load time of my View being slow. I added logging at various points within the controller and the controller code executes in around 12ms. So I added logging at the top of my View. There is consistently a 4-6 second delay from the time my controller code completes to the time the view begins to load:

OnActionExecuted – 7/23/2024 3:17:08 PM <- Last entry from end of ActionResult method.

RenderBegin – 7/23/2024 3:17:14 PM <- At the top of _Layout

This is the code from Program.cs:

    var builder = WebApplication.CreateBuilder(args);
    connectionString = builder.Configuration.GetConnectionString("DefaultConnection") ?? throw new InvalidOperationException("Connection string 'DefaultConnection' not found.");

    // Get the scopes from the configuration (appsettings.json)
    var initialScopes = builder.Configuration.GetValue<string>("DownstreamApi:Scopes")?.Split(' ');
    // Add services to the container.
    builder.Services.AddAuthentication(OpenIdConnectDefaults.AuthenticationScheme)
        .AddMicrosoftIdentityWebApp(builder.Configuration.GetSection("AzureAd"))
        .EnableTokenAcquisitionToCallDownstreamApi(initialScopes)

.AddMicrosoftGraph(builder.Configuration.GetSection("DownstreamApi"))
.AddInMemoryTokenCaches();

    builder.Services.AddFeatureManagement();
    builder.Services.AddScoped<PreserveStateFilter>();
    builder.Services.AddHangfire(configuration => configuration
           .SetDataCompatibilityLevel(CompatibilityLevel.Version_180)
   .UseSimpleAssemblyNameTypeSerializer()
   .UseRecommendedSerializerSettings()
   .UseSqlServerStorage(connectionString));
    builder.Services.AddControllersWithViews(options =>
    {
        var policy = new AuthorizationPolicyBuilder()
            .RequireAuthenticatedUser()
            .Build();
        options.Filters.Add(new AuthorizeFilter(policy));
    }).AddRazorOptions(opt => {
        opt.ViewLocationFormats.Add("/Views/Forms/{0}" + RazorViewEngine.ViewExtension);
        opt.ViewLocationFormats.Add("/Views/ArchivedForms/{0}" + RazorViewEngine.ViewExtension);
    });

    builder.Services.AddSession(options => {});
    builder.Services.AddSingleton<IHttpContextAccessor, HttpContextAccessor>();

    builder.Services.AddHangfireServer();
    

    builder.Services.AddRazorPages()
        .AddMicrosoftIdentityUI();


    var app = builder.Build();

    // Configure the HTTP request pipeline.
    if (!app.Environment.IsDevelopment())
    {
        app.UseExceptionHandler("/Home/Error");
        // The default HSTS value is 30 days. You may want to change this for production scenarios, see https://aka.ms/aspnetcore-hsts.
        app.UseHsts();
    }
    Serilog.Log.Logger = new LoggerConfiguration()
          .ReadFrom.Configuration(app.Configuration)

             })
         .CreateLogger();
