ReadyToRun Benchmark

Sample solution for evaluating lambda cold-start time reduction that comes from using ReadyToRun images in .NET core 3.1.

Requirements

• docker
• dotnet sdk 3.1
• aws cli

Content

• Functions + Dependencies - sample lambda function and some external depenencies to make the deplyment package larger
• Deploy - Dockerfile for building the lambda with ReadyToRun enabled and a PowerShell script that performs actual packaging and deployment

Usage

Adjust Deploy/deploy.ps1 script and provide s3 bucket name for the deployments. Run the script to build the project and run it twice to deploy two versions of the lambda function to AWS:

./deploy.ps1 lambda-stack-r2r $True # R2R enabled
./deploy.ps1 lambda-stack-std $False # R2R disabled

Use our cold-start measure app to measure the cold-starts:

.\Rozchmurzeni.ColdStartMeasure.exe lambda-stack-r2r-DoWork-1H059DI1YXHW
.\Rozchmurzeni.ColdStartMeasure.exe lambda-stack-std-DoWork-YHYKZG9H9ETX
