Description

We were unable to upgrade from angular 9 to 11 last year. After doing the migration the builds are taking around an hour and ng serve is taking around 10minutes to start and then a few minutes to recompile.

🔬 Minimal Reproduction

The project is quite large. I may be able to share it on my private github if necessary.

🔥 Exception or Error

I saw this issue raised: #17557 that was able to spit out the webpack timings but I tried the same command and didn’t get anything. Here are some logs from that command though:
