Razor templates - First startup slow (precompile?)

.NET Core
1

Hi there!

While running ServiceStack, dotnet core, on a Raspberry Pi, i noticed that first load of my razor view pages is slow.
Once loaded, it goes like a rocket.

I don’t have any specific settings for precompilation, what-so-ever.
Is this solved by setting some options for pre-compilation of razor views, and what would be the recommended setup?

A dirty fix would be the application having to call its-self once during boot, so it’s loaded. (i know…)

What’s best ?

Is this using Mono or .NET Core? Mono is really slow compiling Razor pages, if you’re using Mono I’d switching to .NET Core pretty much for all projects in future.

Pre-compiling the Razor views will help, there’s an example of using pre-compiled Razor Views in RazorRockstars.CompiledViews.

Otherwise I recommend checking out http://templates.servicestack.net as an alternative to Razor, Template pages don’t need to be compiled as it just uses compiled expressions which will be much faster to load.

I know, Mono is tied to my some of my posts, but i have made my switch to dotnet core in the past months voor my main project. So; its .NET Core!

I will the check pre-compile razor views article. I don’t feel like switching to Templates as my whole front-end is written in Razor views.

Many thanks.

@salorob Just in case, if you are deploying .NET Core 2.0 to a docker environment, a work around is needed for pre-compiled razor views.

You want to use a work around which builds the precompiled views when not publishing to a stand alone deployment.

Issue is also documented here in the note.
