Performance test for package Microsoft.Extensions.Caching.SqlServer

Introduction

This is a repo to test the performance after some optimizations in Microsoft.Extensions.Caching.SqlServer

Running the test

This test assumes that you have a SQL server instance running locally. To use a SQL server instance running in another server, change the connection string accordingly.

1. Create the cache database. Type in command line

sqlcmd

Run in the command prompt these lines one by one

CREATE DATABASE CacheSampleDb
go
exit

2. Install the tool to create the objects needed in the database

dotnet tool install --global dotnet-sql-cache --version 2.1.1
dotnet sql-cache create "Server=localhost;Initial Catalog=CacheSampleDb; Trusted_Connection=True;" "dbo" "CacheSample"

3. Then run the test applications and see the execution times (should take less than 30 seconds)

Assuming that the current directory is root and starting with the non optimized test:

cd current-not-optimized-package
dotnet restore

And run multiple times:

dotnet run

Then go to the path that uses the optimizations:

cd ..\optimized\perf-test
dotnet restore

And run multiple times:

dotnet run
