Reindexing entire library each time I start VS Code

[AndyGHenderson]

Issue Type: Performance Issue

I believe this was triggered by me upgrading my installed version of PHP from 7.1 to 7.3.

Now every time I open Code it indexes every .php file I have showing the message 'Parsing file...' for each one in the output window.

I use VS Code to manage several sites and each one uses a variety of WordPress plugins. That means a lot of files. I'm unsure what the indexing is doing, but I suspect it's treating my entire folder tree (containing several sites) as a single project - which is bound to yield incorrect results. All that activity is unnecessary - I don't need it and have been doing fine without it up to now.

So - I'm looking either for a way to turn it off or have VS Code remember the results of the last index so it doesn't have to repeat it on every reload.

Same issue, but running VS Code on Linux (CentOS 7), PHP 7.3, extension v 2.3.13. Managing Moodle code (many files)

Same here, reindexing vendor folder every time opening a project. Windows10 / VS Code 1.55.1/ PHP 7.4.7. Would be nice if cached until next composer update / install.
