Description

Similarly to this Atom bug, cpptools discovering files is too slow when the files are hosted on nfs. Discovering 20k files takes about a minute, during that time the db icon will be present and sometimes the hotflame icon will be visible too. Intellisense is laggy or completely unusable during that time.
https://github.com/atom/atom/issues/1766

I tested vscode with cpptools on Windows and on Linux without sshfs and it's super fast, when I start vscode it takes just a few seconds for the db icon to disappear.

I thought the language server in cpptools is a c++ application, why it's taking that long to discover files?

Research direction

Reproduce file discovery over sshfs or NFS with the reported Redhat 7.3 and VS Code setup, using a workspace containing about 20k files. Observe discovery time, the database and hotflame indicators, and IntelliSense responsiveness. Done means discovery completes promptly and IntelliSense remains usable on remote files without regressing local performance.
