# .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.

## MVC + Templates
Let’s run one more benchmark, spawn `1000000 requests` but this time we expect HTML generated by templates via the view engine.
* Time to complete the `1000000 requests` - smaller is better.
* Reqs/sec - bigger is better.
* Latency - smaller is better
* Memory usage - smaller is better.
* Throughput - bigger is better.
.NET Core MVC with Templates Application ran for **1 minute and 20 seconds** serving **11738.60** requests per second with **89.03MB/s** within **10.10ms** latency in average and **1.97s** max, the memory usage of all these was ~193MB (without the dotnet host).
Iris MVC with Templates Application ran for **37 seconds** serving **26656.76** requests per second with **192.51MB/s** within **1.18ms** latency in average and **22.52ms** max, the memory usage of all these was ~17MB.
# .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", targeting to a dynamic registered route path, responds with a simple "value" text.
* 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.
Node.js (Express) Application written using **12 code of lines** ran for **1 minute and 25 seconds** serving **11665.30** requests per second with **3.14MB/s** within **10.72ms** latency in average and **112.10ms** max.
## Sessions
Spawn `5000000 requests` with 125 different "threads" targeting a static request path, sets and gets a session based on the name `"key"` and string value `"value"` and write that session value to the response stream.
* Time to complete the `5000000 requests` - smaller is better.
* Reqs/sec - bigger is better.
* Latency - smaller is better
* Throughput - bigger is better.
.NET Core with Sessions Application ran for **2 minutes and 40 seconds** serving **31844.77** requests per second with **14.51MB/s** within **4.02ms** latency in average and **0.96s** max.
Iris with Sessions Application ran for **1 minute and 15 seconds** serving **66749.70** requests per second with **20.65MB/s** within **1.88ms** latency in average and **1.94s** max.
Node.js (Express) with Sessions Application ran for **15 minutes and 47 seconds** serving **5634.27** requests per second with **1.48MB/s** within **22.17ms** latency in average and **119.08ms** max.
