serve rebuild speed problem between 9rc.1 and 9rc.2 and 9rc.3 #33986
Description
🐞 Bug report
Command (mark with an x)
- serve
Is this a regression?
Yes, in 9rc1, our app (on serve ivy+aot) each rebuild is <2seconds
In 9rc2 app rebuild ~6seconds
Now with rc3, if I trigger rebuild by adding one character in file+save (5 times) rebuild always take >15seconds
1.I was on 9rc2 then use ng update to go to 9rc3 for all packages (cli and core ...)
2. After that I run --migrate-only --from=8 --to=9
3. ng s ( ivy and aot is enabled)
🔥 Exception or Error
