OrchardCore: I'm experiencing very slow razor compilations (at runtime), both on RC1 and RC2

Hello,

I understand no one else is experiencing this which means it is very likely down to the environmental setup on my machine, however I would appreciate it if anyone has any ideas as to how I can diagnose what the root issue may be? I first noticed this issue when upgrading our projects to RC2, so I attempted to replicate it using the OrchardCore repository, and I could.

Here are the following steps I used to run into this issue;

  1. Cloned the OrchardCore git repository.
  2. Checked out the RC2 tag,
  3. Launched the OrchardCore.Cms.Web project.
  4. Created a SQL Server db and installed “The Agency” setup recipe
  5. Went to /Admin using the credentials I used for the Orchard setup.

I then restarted to enable detailed logging, and went back to the /Admin path to see what the compilation times were like, attached is the full logging from that request with the logging level set to debug, this request took 45 seconds to complete.

AdminRequest.log

As always happy to provide more info if needed.

Here is my dotnet --info output:

To install additional .NET Core runtimes or SDKs:
  https://aka.ms/dotnet-download

I have a 4c/8t intel cpu and 16gb of ram, and neither of those resources appear to be the bottleneck.

step by step

First, as said in the related PR, for rc2 apps you can set PreserveCompilationReferences to false as you tried and then reference the runtime compilation package directly from your app like this

<PackageReference Include="Microsoft.AspNetCore.Mvc.Razor.RuntimeCompilation" ExcludeAssets="build;buildtransitive" />
