title: Delphi IDE (Code Insight) extremely slow on a semi large project
body: <p>I've been working on a project that I update from time to since a few years through the various Delphi versions, currently on 10.3.1, and lately as I've been adding more features the editor is becoming progressively slower to the point I can barely type if Code Insight pops out, the editor keeps freezing for 1-3 seconds at a time, CTRL+Space takes also a while, compiling takes a few seconds until it actually starts, and clicking on "Save All" freezes everything as well for a few seconds.</p>
  
  <p>I've read other questions about this issue and removed any unused units, as well as moving all I could after the implementation, but it has made no difference whatsoever.</p>
  
  <p>Any tips? (already using IDE Fix pack, SSD, fast PC)</p>
