Below is a list of the performance updates made in Angular 9:
  • We are binding the updated benchmark while also converting all the node-based parameter to be used as a testing harness.
  • I was avoiding metamorphic reads during the process of property binding.
  • Minimizing repeated lview reads inside the pipe instructions.
  • Eradicating any unnecessary DOM reads in the styling instructions.
  • Initializing TNode inputs/outputs on the very first creation pass for Ivy.
  • The limit TNode.outputs reads for Ivy.
  • The language-service keeps the analyzedModules cached when source files are not changed.
