![]() Summary: clangd supports a -j option to limit the amount of threads to use for parsing TUs. However, when using -background-index (the default in later versions of clangd), the parallelism used by clangd defaults to the hardware_parallelisn, i.e. number of physical cores. On shared hardware environments, with large projects, this can significantly affect performance with no way to tune it down. This change makes the -j parameter apply equally to parsing and background index. It's not perfect, because the total number of threads is 2x the -j value, which may still be unexpected. But at least this change allows users to prevent clangd using all CPU cores.

//===----------------------------------------------------------------------===// // Clang Tools repository //===----------------------------------------------------------------------===// Welcome to the repository of extra Clang Tools. This repository holds tools that are developed as part of the LLVM compiler infrastructure project and the Clang frontend. These tools are kept in a separate "extra" repository to allow lighter weight checkouts of the core Clang codebase. This repository is only intended to be checked out inside of a full LLVM+Clang tree, and in the 'tools/extra' subdirectory of the Clang checkout. All discussion regarding Clang, Clang-based tools, and code in this repository should be held using the standard Clang mailing lists: http://lists.llvm.org/mailman/listinfo/cfe-dev Code review for this tree should take place on the standard Clang patch and commit lists: http://lists.llvm.org/mailman/listinfo/cfe-commits If you find a bug in these tools, please file it in the LLVM bug tracker: http://llvm.org/bugs/
