Safari 5.x memory leak, bad performance - a disaster

It's enough. I tried really hard, but I can't. Safari 5.x is unusable for me under both, Lion and Snow Leopard.
Reasons:

  • Safari consumes more than 1.5 GB memory in scenarios, where Safari and Chrome are still under 200 MB i.e. it has at least one memory leak
  • The leak has severe impact on the overall system performance, because it forces other apps' data to swap out
  • Loading pages is slower than in other browsers
  • Reopening tabs takes ages
  • HTML5 video replay CPU consumption is unacceptably higher than with Flash (YouTube-based comparison)
