High memory usage on serve #8254

I noticed a high memory usage using the last version of CLI when runningng serve. It starts with a normal amount of memory allocated. And then for every change made to the project files, it seems that the previous memory allocated for the build is not freed and the memory keeps growing until I have to stop the process and start again.

Node: 7.6.0
OS: win32 x64

Repro steps.
I would need to try on a new generated project if it does the same thing.

Here is 2.6G of RAM allocated for the serve process.

Duplicate of #5613

With 1.5 and Angular 5 a new compiler is used so this may not be a dupe.
@fknop Can you try with the latest RC of 1.5?
fknop commentedon Oct 31, 2017
@clydin Is rc6 not already the latest rc ?
Edit: ok nevermind, I just saw rc-8 was out, I was looking at the releases on GitHub and there was no changelog.
I'll will try later then!
fknop commentedon Oct 31, 2017
@clydin High memory usage is still there but it seems to grow much slower.

Also being tracked by #8259, reverting some behavior in next RC/final (keep an eye out for it, PR is #8267)
hansl commentedon Oct 31, 2017
I'm going to do another RC today for that PR and the sourcemaps ones.

I noticed that it eats a lot of memory even in the release build. Can anyone else reproduce that also?

For discussion about the amount of memory used by
ng serve, please use #5613 instead. For the memory usage inng build --prodplease use #5618.angular-automatic-lock-bot commentedon Sep 7, 2019
