.NET Core 2.0 reached end of life on October 1, 2018. This means .NET Core 2.0 is no longer supported and updates will no longer be provided. We recommend moving to .NET Core 2.1, our long term support (LTS) release.

.NET Core 3.0 Perf Timing for basic operations

The following are rough results, comparing .NET Core 3

Installing .NET Core on Linux ARM64

The following intructions can be used to install .NET Core on Linux ARM64.

Pro tip: Check out .NET Core Docker files to determine the exact instructions for installing .NET Core builds, for example .NET Core 3.1 ARM32 SDK Dockerfile.

Installing .NET Core Globally

The following instructions install the latest .NET Core globally. It isn't required to do that, but it provides the best experience.

.NET Core Docker Limits Test

Docker enables you to limit a container's resources. This control is great for high-density hosting and other low-resource scenarios. Developers have the expectation that the application platform respects these limits and does its best to work within them.

I wrote a crude test framework to determine how .NET Core behaves when various resource limits are set. The following are the results.

The testing varied the following:

Host OS
Server vs Workstation GC

	// Called whenever an EventSource is created.
	protected override void OnEventSourceCreated(EventSource eventSource)
	{
	// Watch for the .NET runtime EventSource and enable all of its events.
	if (eventSource.Name.Equals("Microsoft-Windows-DotNETRuntime"))
	{
	EnableEvents(eventSource, EventLevel.Verbose, (EventKeywords)(-1));

	// get access token using ADAL.NET
	var authContext = new AuthenticationContext(authority);
	var authResult = await authContext.AcquireTokenAsync(appUri, clientCredential);
	// setup connection to SQL Server
	var sqlConnection = new SqlConnection(connectionString);
	sqlConnection.AccessToken = authResult.AccessToken;
	await sqlConnection.OpenAsync();
