Reconsider usage of `unordered_set/map`
Try opened this issue · comments
While profiling with debug build, notice, that mingw spends too much time in deallocation of memory and maps in particular.
Tested locally:
changing std::unordered_set<std::uint32_t> bsp_tree:leaf_polygons; to sorted array std::vector<std::uint32_t> gives about 3x boost to load-time. From 110022ms to 36418ms
Hm I'll look into it. phoenix itself takes about 4 seconds to load a world in debug mode though so the 7 remaining seconds are just OpenGothic's conversion stuffs. I'd recommend running in release mode with debug symbols (RelWithDebInfo in CMake) anyways. With that load times are >200 ms.
RelWithDebInfo
No, it's horrible way of debugging anything - lack of glsl debugging is bad enough already)
Okay, just to make this reproducible for me, which version of MinGW-w64 are you using and did you add any additional compile flags to the build different from the default (that includes flags added by your build tool, e.g. VisualStudio)?
MinGW 11.2.0 64-bit for C++ (installed with Qt-sdk)
CMake generator: Ninja
In principle can prepare PR somewhat later
