Over the past month of trying out Intel Alder Lake processors on Linux, one of the questions that has come up a few times but not readily disclosed is whether it's still worthwhile on this latest-generation process to boot with "mitigations=off" to disable CPU security mitigations to help squeeze out some otherwise lost performance. Here are some benchmarks to answer that questions.

When debugging graphics driver/API issues or performance profiling and relying on shader dumps, the size of such dumps can quickly add up due to all of the state collected, etc, but also inefficiencies when not within contiguous memory. Fortunately for Mesa's Radeon Vulkan driver "RADV" for pairing with the Radeon GPU Profiler there is a significant improvement that just landed for yielding smaller file sizes...
