title: VSCode slow to open and highlight large log files
body: <p>VSCode slow to open and highlight large log files</p>
  
  <p>I use VSCode to open large log files with the log highlighter syntax. These log files are very large, often a couple hundred megabytes. I switched from Notepad++ to VSCode for all the features. Notepad++ usually opened the files okay but lacked the highlighting benefits.</p>
  
  <p>The new VSCode updates asked me to increase memory size which I quadrupled.</p>
  
  <p>However some logs either take a while to highlight or never do at all.</p>
  
  <p>Is there anyway to either speed this up or get this to work a bit better? Should I open a github issue? </p>
  
  <p>I would really like to use VSCode for these logs but it is annoying...
  Resources on PC are not an issue.</p>
