[Bug]: Slow startup on larger projects

[cgrantnz]

Version

11.0.0-rc.3

Steps to reproduce

1. Clone https://github.com/callumelgrant/jest-preset-angular
2. Run yarn test in the Angular 13 example.

Expected behavior

It would be nice to see a test run time more similar to the earlier versions of jest-preset-angular.

Actual behavior

Running yarn test takes ~65 seconds from a cold cache after adding lodash-es. Is there any way to reduce this?

Additional context

After adding more packages to the solution the transformation time seems to increase considerably - in our yarn workspace running yarn test on a cold cache takes 20 minutes before starting to run tests.

Environment

System:
    OS: Windows 10 10.0.19042
    CPU: (16) x64 AMD Ryzen 7 PRO 4750U with Radeon Graphics
  Binaries:
    Node: 16.13.0 - C:\Program Files\nodejs\node.EXE
    Yarn: 1.22.15 - C:\Program Files (x86)\Yarn\bin\yarn.CMD
    npm: 8.1.0 - C:\Program Files\nodejs\npm.CMD
  npmPackages:
    jest: ^27.3.1 => 27.3.1

Currently workaround is:

• Switch to isolatedModules: true which will disable type checking.
• Add moduleNameMapper for lodash-es, see How to set transformIgnorePatterns to fix "Jest encountered an unexpected token" nrwl/nx#812 (comment)

it is a performance issue which exists for a long time, not specific to 11.0.0-rc.3

[ahnpnl]

The provided solution will solve partially the problem only as we rely on ts-jest about performance with type checking.
