Serving with AOT takes 10+ minutes

[masaanli]

Please provide us with the following information:

Call I did:

node --max_old_space_size=8192 ./node_modules/.bin/ng serve --env=prod --aot=true

in v24 of the Cli it was just taking 50 seconds?

OS?

Windows 7, 8 or 10. Linux (which distribution). Mac OSX (Yosemite? El Capitan?)
MacOS Siera

Versions.

Please run ng --version. If there's nothing outputted, please run in a Terminal: node --version and paste the result here:
25.5 / 6.9.1

Repro steps.

Was this an app that wasn't created using the CLI? What change did you do on your code? etc.

The log given by the failure.

Normally this include a stack trace and some more information.

Mention any other details that might be useful.

Thanks! We'll be in touch soon.

Can you provide console output of beta.24 vs beta.25 to get a better understanding of what's happening?

Also, a production AOT build is never going to be "fast". It's meant to optimize the output as much as possible. So except for a test scenario, it's not going to provide a very productive development experience in combination with serve.

[masaanli]

@clydin the output is nothing more then 33 chunks being generated?

Yeah I know what you are saying, but sometimes you wanna test AOT on development environment too.

1 minute waiting was ok, but now it sometimes is taking 18 minutes max!

@hansl any clue on why this changed so drastically?

[CanKattwinkel]

I just updated my project from beta.24 to 25.5. There was no performance losses for me when running
node --max_old_space_size=8192 ./node_modules/.bin/ng serve --env=prod --aot=true

No performance loss on MacOS for me, in fact things are working a little better than before.

You re-initialized the project after upgrading, correct?

[hansl]

I haven't seen any loss in performance for AOT, but it might be depending on the app itself.

@masaanli Could you provide an example application that we could test on? I'm really curious about such a performance hit and we definitely want to investigate.

Thanks!

@hansl it;s a application with 100+ pages and there is a lot of stuff. So I don't know how to reproduce it in a plunker I think a Plunker with SystemJS loading time is already 5 minutes hehe.

Teamviewer is possible?
