title: Visual Studio Code - lagging when typing
body: <p>I have just installed Visual Studio Code together with the Java Extension Pack. However, when I opened my first file and started typing, the text I type appears after a delay - reaching up even one second. <br>
  I have a hunch that it might be due to the number of processes going behind the editor, like real-time syntax checking, autocompletion, code hints et cetera. Perhaps the laptop I am working at simply cannot handle that much. These are the parameters of my current machine: <br>
  Processor: Intel(R) Caleron(R) CPU N3350 (1.10 GHz) <br>
  RAM: 4 GB <br> <br>
  I have another hunch that it may be due to the processor. <br><br>
  So, are there a ways to switch off these facilities like real-time error-checking? If not, what other IDEs for Java could you reccomend? (Apart from Eclipse)</p>
