When loading the sdk, a compilation of dart2js and a big internal app
without lazy loading (but with useGrowableLists: false though that
part shouldn't matter) I see these changes:
Loading the sdk: Saving ~1.17 MB Public and ~0.33 MB Private.
A total of ~1.5 MB.
Loading a compile of dart2js: Saving: ~7.0 MB Public and ~1.1 Private.
A total of ~8.1 MB.
Loading a compile of a big internal app: Saving ~74.7 MB Public and
~25.4 MB Private.
A total of ~100 MB.
Specifically, when loading a big internal app I see these changes:
Change, without lazy loading (and useGrowableLists: false):
Current memory: -122.88 MB
Peak memory: -92.16 MB
Heap: -102.4 MB / -92.16 MB
_PublicNames: -74.75 MB (2 mio+ fewer)
_PrivateNames: -25.4 MB (800,000+ fewer)
Change, with lazy loading (and useGrowableLists: false):
Current memory: +10.24 MB (yes, more).
Peak memory: +10.24 MB (yes, more).
Heap: +2.2 MB / +2.5 MB (yes, more)
_PublicNames: -0.76 MB (20,000+ fewer)
_PrivateNames: -11.3 KB (some hundred fewer)
