cpptools very slow for large project

[piterzhang]

1.when I use cpptool to read linux code,the speed of go to function define is very slowly and some times can't work
2. then i try gun global in vscode to read linux code ， surprised ,very fast. but used gun global cant used cpptool,I need cpptool to debug also

Q:

1.can give user a selectc used cpptool or gun global

2.if cpptool can work like gun global, generate data base before read code
let it fast when read large project

If you want to use another extension for language service processing and cpptools for debuggng you can set C_Cpp.intelliSenseEngine to "disabled".

For the Go to Definition speed, it could be caused by different issues. You could open an issue https://github.com/microsoft/vscode-cpptools/issues if you want us to investigate the performance further.
