I'm working on a C Linux kernel module, and the editor gets extremely slow on the main keyboard driver file. It doesn't effect moving by the mouse, but does effect Vim emulation with the systems vimrc. It's about 1,500 lines of code for the file. I'm using a hacky CMakeLIsts.txt to let me build and navigate the source for a Make based project.
I notice it happens with PyCharm as well with ideavim, when I'm working on the python parts of the projects.
The project in question causing the issues is: https://github.com/terrycain/razer-drivers
Which benchmarks do you need to pinpoint this?
