The same issue on Windows 11. Intellisense is horribly slow and never finishes (for a source file https://github.com/anoban/cpp23/blob/main/rvopt.cpp with just 42 lines of C++ code it takes about 12 minutes immediately after cold start). On the other hand
clangdwith VSCode insiders does everything in a fraction of a second. I'm not trying to downplay the usefulness of this extension because this is the only extension that provides decent C, C++ debugging experience on Windows but it has become obnoxiously sluggish. Is there a way to fix this from my end? I used to allow it to use memory liberally for caching but it never helped and sometimes consumed up to 2 GiBs of memory so I've now limited those options.Originally posted by @anoban in #12169
