Web load/store buffer size tester Attempts to find limits for in-flight loads and stores, which correspond to load/store buffer sizes on some hardware. This "tool" is mostly for entertainment purposes, at least for now. Please don't trust it. The results on M1 are complicated by out-of-order store commit. I've written more about them on my blog. Loads on Zen 3 are confusing, I believe others have looked into this more.
