Visual Studio Code is very slow compared to Eclipse?

I've been using Visual Studio Code as a source code editor for more than a year now and Eclipse whenever I run the applications in the simulator and exporting the app (or creating an IQ file), but now in latest SDK's it looks like Eclipse has been deprecated and I have to use the Visual Studio Code in running and exporting the app, the problem is my Visual Studio Code is very slow in running the app (it is like 20 times slower than Eclipse) and the exporting is like taking forever (I tried exporting a project but it never finished), I've been thinking reinstalling my Visual Studio Code as a solution but not sure if it will work, has anyone experienced the same problem?
