angular: large angular application v9 build extreamly slow >20m

we are testing our application with v9 rc7 and build is taking more than 20 minutes. which is extremely slow compared to v8 build time. (ng serve is also slow compared to v8)

below is the output from ng build command from our CI server for v9 build.

Actually I looked into it just now already. It’s indeed significantly slower, I am seeing 152s for the VE build and 944s for the Ivy build. The Ivy build process skyrocketed to ~33GB of RAM (with debugger and profiler attached) and that made me remember #33532. So, I turned off fullTemplateTypeCheck and indeed, this would resolve the issue.

The performance issue with fullTemplateTypeCheck has been fixed in TypeScript 3.8 dev builds (see microsoft/TypeScript#35205 and microsoft/TypeScript#35332), but that has not yet been released and is also not supported by Angular. I tried bumping the TS version in your app but that resulted in some compilation errors, so I decided to just disable fullTemplateTypeCheck. This brings the build time to be on par with the VE build, after excluding the time that ngcc takes. I have not looked into locating the template that is taking so long to compile, as that’s quite hard to identify.

I will be looking into where the time is spent some more, as this is an interesting project to profile.

Build size uncompressed goes from 26.4 MB with VE to just 10.3 MB with Ivy❗️Hopefully it still works…

@JoostK on the note of Angular not supporting the version of typescript. Do you know when angular will be upgrading it’s support. Also would it be possible for us to bypass the typescript version check and allow us to experiment on different version. Just without support

@Jordan-Hall you can set disableTypeScriptVersionCheck to true in tsconfig.json under angularCompilerOptions. Also, TypeScript 3.8 has not yet been released; I don’t know when Angular can update to it. At the very least, it won’t happen before 9.1.
