CodeLLDB uses a huge amount of RAM

Open namnq-sipher opened this issue 9 months ago • 5 comments

OS: Windows 11 Pro VSCode version: Cursor 0.46 CodeLLDB version: 1.11.4 Compiler: clang Debuggee: Unreal Engine 5.5 Editor

codelldb.exe uses a 40-50GB RAM.

The same project on macOS (using Cursor IDE too)

LLDB optimizes access to DWARF debug info by loading it on demand.
PDB, accessed via MSDIA, which preloads everything into memory, AFAIK.

Ah, you can try using LLDB's native PDB reader implementation: add "lldb.adapterEnv": {"LLDB_USE_NATIVE_PDB_READER": "1"} to your workspace settings. It's probably more buggy than MSDIA library though.

I can partially confirm this is the case for a medium sized project. In my case, it slows down codelldb too much with high CPU usage. Memory is relatively high (1.1 GB in my case) but I wouldn't say there is a leak. I'm also on Windows 11 Pro. Exporting LLDB_USE_NATIVE_PDB_READER=1 environment value does indeed solve my problem.
