For various GPU benchmarks from the likes of Vulkan compute and Llama.cpp to OpenGL graphics, there wasn't too much of a difference observed out of Liquorix. Though part of the focus on Liquorix is on responsiveness that is harder to measure in these benchmarks.

With the Vulkan-based AI inferencing with Llama.cpp, there wasn't much of a performance difference but for CPU-based AI inferencing the upstream Linux 6.18 LTS kernel was much faster.

👁 Timed LLVM Compilation benchmark with settings of Build System: Ninja. 6.18.2-2-liquorix was the fastest.

👁 Timed LLVM Compilation benchmark with settings of Build System: Unix Makefiles. Linux 6.18 Upstream was the fastest.

👁 Timed PHP Compilation benchmark with settings of Time To Compile. Linux 6.18 Upstream was the fastest.

👁 Timed Erlang/OTP Compilation benchmark with settings of Time To Compile. 6.18.2-2-liquorix was the fastest.

For those doing a lot of code compilation, there wasn't too much of a difference observed between these Linux kernel flavors.
