...It walks arrays using different strides and working-set sizes so you can observe when access patterns overflow cache or TLB capacity. By timing tight loops and varying parameters, the program reveals step-changes in latency that map to cache lines, page sizes, and TLB coverage. It is intentionally minimal so you can modify page sizes, strides, or pointer-chasing strategies to run experiments on different machines and kernels. The code is useful for teaching, hardware bring-up, or validating assumptions about huge pages and NUMA placement. Rather than providing a plotting framework, it prints timings that you can collect and graph with external tools to visualize cache/TLB boundaries.

...The command forms are terse, and it allows either use as an immediate mode debugger of drives or it can be used to form full testing scripts. It is fairly compact at 4069 lines for the main module, and features plug in IO modules at about 500 lines each for both Windows and Linux, and DOS/BIOS. The project has been running at 6-20 downloads per week. Please if you have time write a short review or leave user comments in the discussion forums. Thank you.
