# .NET Core MVC vs Iris MVC

The first test will contain a simple application with a text response and the second will render templates + a layout.

## Simple 

We will compare two identical things here, in terms of application, the expected response and the stability of their run times, so we will not try to put more things in the game like `JSON` or `XML` encoders and decoders, just a simple text message. To achieve a fair comparison we will use the MVC architecture pattern on both sides, Go and .NET Core.

### Summary

* Time to complete the `5000000 requests` - smaller is better.
* Reqs/sec - bigger is better.
* Latency - smaller is better
* Throughput - bigger is better.
* Memory usage - smaller is better.
* LOC (Lines Of Code) - smaller is better.

.NET Core MVC Application, written using 86 lines of code, ran for **2 minutes and 3 seconds** serving **40226.03** requests per second within **3.09ms** latency in average and **169.12ms** max, the memory usage of all these was ~123MB (without the dotnet host).

Iris MVC Application, written using 27 lines of code, ran for **47 seconds** serving **105643.71** requests per second within **1.18ms** latency in average and **22.01ms** max, the memory usage of all these was ~12MB.

#### Update: 20 August 2017

As [Josh Clark](https://twitter.com/clarkis117) and [Scott Hanselman‏](https://twitter.com/shanselman)‏ pointed out [on this status](https://twitter.com/shanselman/status/899005786826788865), on .NET Core MVC `Startup.cs` file the line with `services.AddMvc();` can be replaced with `services.AddMvcCore();`. I followed their helpful instructions and re-run the benchmarks. The article now contains the latest benchmark output for the .NET Core application with the change both Josh and Scott noted.

The twitter conversion: https://twitter.com/MakisMaropoulos/status/899113215895982080

For those who want to compare with the standard services.AddMvc(); you can see the old output by pressing [here](screens/5m_requests_netcore-mvc.png).

## MVC + Templates

Let’s run one more benchmark, spawn `1000000 requests` but this time we expect HTML generated by templates via the view engine.

### .NET Core MVC with Templates

# .NET Core (Kestrel) vs Iris

_Monday, 21 August 2017_

This time we will compare the speed of the “low-level” .NET Core’s server implementation named Kestrel and Iris’ “low-level” handlers, we will test two simple applications, the first will be the same as our previous application but written using handlers and the second test will contain a single route which sets and gets a session value(string) based on a key(string).

## Simple

Spawn `1000000 requests` with 125 different "threads", tagrget to a dynamic registered route path, responds with a simple "value" text.

### .NET Core (Kestrel)

```bash
$ cd netcore
$ dotnet run -c Release
Hosting environment: Production
Content root path: C:\mygopath\src\github.com\kataras\iris\_benchmarks\netcore
Now listening on: http://localhost:5000

  Latency        1.28ms   682.63us    61.04ms
  HTTP codes:

```

### Iris

```bash
$ cd iris
$ go run main.go
Now listening on: http://localhost:5000
Application started. Press CTRL+C to shut down.
```

```bash
Bombarding http://localhost:5000/api/values/5 with 1000000 requests using 125 connections

### Summary

* Time to complete the `1000000 requests` - smaller is better.
* Reqs/sec - bigger is better.
* Latency - smaller is better
* Throughput - bigger is better.
* LOC (Lines Of Code) - smaller is better.

.NET Core (Kestrel) Application written using **63 code of lines** ran for **10 seconds** serving **97884.57** requests per second with **17.73MB/s** within **1.28ms** latency in average and **61.04ms** max.

Iris Application written using **14 code of lines** ran for **8 seconds** serving **117917.79** requests per second with **21.93MB/s** within **1.06ms** latency in average and **19.03ms** max.

## Sessions

Spawn `5000000 requests` with 125 different "threads" target a static request path, sets and gets a session with name `key` and string value `"value"` and write session value that to the response stream.

### .NET Core (Kestrel) with Sessions
