VSCode with cpplint slowing down over time

Did someone of you guys also experience massive slow downs when using Platformio in VSCode with the cpplint VSCode extension installed and can give me some advice?

After a fresh start of VSCODE/Platformio everything is fine, but after some time of using it with frequent opening/closing of source files and switching editor tabs VSCode is slowing more and more until I will have to wait very long before any editing action is possible in a source file again. As long as I will stay in that tab, editing is quite normal, but as soon as I will go into another tab, the waiting time is again longer than before.

VSCode sometimes warns about the cpplint extension using a lot of resources. The ultimate effect is VSCode hanging up itself - only a task kill will resolve that.
