"Go To Symbol in Workspace..." searchs are not "snappy" on large projects

[noam-zur]

Bug type: Language Service

OS and Version: Windows10 (Version 2004) VS Code Version: 1.58.2 C/C++ Extension Version: v1.5.1 "Go To Symbol in Workspace..."(CTRL+T) is very slow on large projects.

As a benchmark, I opened a workspace on Linux code base, and searched for "memory". Results for the first search are abnormally long (~25 seconds). to be handled in another bug report (#7980)

Results for additinal searchs are around ~3s. Since browsing large code bases requires many such searches, non-instant results becomes a burden.

Notes:

I set C_Cpp.intelliSenseEngine to "Tag Parser" (my preferred choice) The workspace was fully parsed before running the search. For comparison, on ** Source Insight IDE , results for the same symbol search are instant (<1s).**

Expected behavior Full Workspace Symbols Search should return results faster (<1s)

A significant update to Go To Symbol has been published in the insiders build - see #11557

This should be addressed in 1.19.4.
