High CPU load when Language Server is integrated in VSCode

[cafe88]

Robot framework language server in VSCode is using very much CPU power in idle.
May be the same error as mentioned in #350

To Reproduce
Install Robot Framework Language
Reload VSCode
Open a .robot file.

Expected behavior
No significant change in processor activity should happen when sitting idle.

Logs:
If logs are needed, i can add them here.
But then I'll have to check it before posting because this is an issue which happens on my PC at work.

OS: Windows 10
Robot Framework Language Server: 0.16.0

This really seems like a duplicate of #350, so, I'm going to close this one.

Note: I added comments at: #350 (comment) so that I can get some further information to know what's actually going on... if you can provide those from your machine and attach it to that issue, that'd be nice.
