ASP.NET 5 is Ten Times Faster?

Home » General Topics » ASP.NET 5 is Ten Times Faster?
ASP.NET MVC Logo

I was watching an introductory video on ASP.NET 5 and MVC 6 from Jon Galloway of Microsoft on ASP.NET 5. One of the things he talks about is the new performance benchmarking suite for ASP.NET 5, which on a simple response.write test shows that ASP.NET 5 using Kestrel rather than IIS is 10 times faster on this test that 4.6 on his laptop.

ASP.NET 5 / MVC 6 Mind Blowing New Features?

This is an interested introductory video, there were a few things that totally blew my mind:

  • MVC 6 does not use .csproj files, it has a wwwroot folder instead for all public files. All other files are considered private.
  • The Html Helpers (that I love) have been changed to use asp- markup (which I am sure I will also love in time)…
  • There is no web.config, apart from the odd time you see it configuring IIS, if IIS is being used in your project. This is replaced by a “Secret Store” and Startup.cs in the code.
  • It appears to be getting even closer to the metal than MVC up to 5 did, with lots of interesting web options. Basically Microsoft are saying if the web supports it they want to support it. Real easy.
  • The new Roslyn compiler allows you to break, change code, and continue when debugging.
  • I was worried at one time, having been a developer when Microsoft brought out Java and tried to customise it, that it might try to customise javaScript when it brought out Windows javaScript apps. However I have seen no sign of this, they appear to be actively supporting best practice javaScript standards and packages. JavaScript is shipped via Grunt, Gulp and Bower, not Nuget anymore.
  • MVC and WebAPI are now merged in MVC 6, previously MVC was dependant on System.Web, which was not the case with WebAPI 2.
  • There are three choices for developers, ASP.NET 4.6, ASP.NET 5 and ASP.NET Core with MVC 6. The last one is cross platform, installable from nuget. Oh and its cross platform, works on Linux and Mac as well. Who would have thought it? I don’t know how the latest Windows servers compare with Linux, Linux on Azure the last time I looked wasn’t super fast – real Linux ran this wordpress site far faster than Azure ever did (maybe the MySql database option I was using). However long ago Linux was far faster than Windows, in the sense it could multi task better and handle more workload by a large factor. I don’t know if this gap has closed or not in recent years, but for sure this kind of thing will put Microsoft under pressure for Windows to keep up, which has to be a good thing.

New Tag Helper Markup

So tag helper markup will in future look like this:

Summary

I’ll be spending quite a bit of time this year with ASP.NET 5, MVC 6 and all the latest web goodies, so I am sure to blog more about this in future. If anybody would like me to blog about specific parts of ASP.NET 5, MVC 6 and related technologies, please comment on the blog, all requests considered.

I have to say… just what is going on at Microsoft? Have I died and gone somewhere else? I know they have been producing so many good things in recent years that have been really difficult to keep up with and that the developers there have come of age and understand real world things like dependencies and the importance of code readability rather than how to produce a really slick demo app that doesn’t scale very easily. What an exciting time to be a developer!

About Phil

I have been working as a software developer since 1983. This blog could have been called "From Fortran 77, C and Cobol to C# in 20 (not so) easy years", but it doesn't sound quite right somehow. Besides I'm talking about what's happened since 2003, not before!

Epics, Features and User Stories

I've been getting more and more emails lately from people confused about the difference between "user stories", "epics" and "features." So I thought this month we'd return and cover some basic--but very helpful--territory by explaining those terms. First, the terms don't matter that much. These are not terms with important specific meanings like "pointer" to a programmer or "collateralized debt obligation" to whomever it is that's important. [...]

Use your own user @ domain for Mastodon discoverability with the WebFinger Protocol without hosting a server

Mastodon is a free, open-source social networking service that is decentralized and distributed. It was created in 2016 as an alternative to centralized social media platforms such as Twitter and Facebook. One of the key features of Mastodon is the use of the WebFinger protocol, which allows users to discover and access information about other users on the Mastodon network. WebFinger is a simple HTTP-based protocol that enables a user to discover information about other users or resources on the internet by using their email address or other identifying information. The WebFinger protocol is important for Mastodon because it enables… [...]

I got tired

I have been blogging here for the last 20 years. Every Tuesday and Thursday, quite consistently, for two decades. But last year, without planning it, I got tired and stopped. Not sure why. It didn't correspond with any life events. Nothing interesting or notable happened. I just stopped. I did find joy on TikTok and amassed a small group of like-minded followers there. I enjoy my YouTube as well, and my weekly podcast is going strong with nearly 900 (!) episodes of interviews with cool people. I've also recently started posting on Mastodon (a fediverse (federated universe)) Twitter alternative that… [...]

Using Home Assistant to integrate a Unifi Protect G4 Doorbell and Amazon Alexa to announce visitors

I am not a Home Assistant expert, but it's clearly a massive and powerful ecosystem. I've interviewed the creator of Home Assistant on my podcast and I encourage you to check out that chat. Home Assistant can quickly become a hobby that overwhelms you. Every object (entity) in your house that is even remotely connected can become programmable. Everything. Even people! You can declare that any name:value pair that (for example) your phone can expose can be consumable by Home Assistant. Questions like "is Scott home" or "what's Scott's phone battery" can be associated with Scott the Entity in the… [...]

JavaScript and TypeScript Projects with React, Angular, or Vue in Visual Studio 2022 with or without .NET

I was reading Gabby's blog post about the new TypeScript/JavaScript project experience in Visual Studio 2022. You should read the docs on JavaScript and TypeScript in Visual Studio 2022. If you're used to ASP.NET apps when you think about apps that are JavaScript heavy, "front end apps" or TypeScript focused, it can be confusing as to "where does .NET fit in?" You need to consider the responsibilities of your various projects or subsystems and the multiple totally valid ways you can build a web site or web app. Let's consider just a few: An ASP.NET Web app that renders HTML… [...]

A Nightscout Segment for OhMyPosh shows my realtime Blood Sugar readings in my Git Prompt

I've talked about how I love a nice pretty prompt in my Windows Terminal and made videos showing in detail how to do it. I've also worked with my buddy TooTallNate to put my real-time blood sugar into a bash or PowerShell prompt, but this was back in 2017. Now that I'm "Team OhMyPosh" I have been meaning to write a Nightscout "segment" for my prompt. Nightscout is an open source self-hosted (there are commercial hosts also like T1Pal) website and API for remote display of real-time and near-real-time glucose readings for Diabetics like myself. Since my body has an… [...]
