The single threaded, async nature does make things complicated. But do you honestly think it's more complica...
Is volatile expensive?
...n the page I see that LoadLoad and LoadStore are effectively no-ops on X86 CPUs. Does this mean that volatile read operations can be done without a explicit cache invalidation on x86, and is as fast as a normal variable read (disregarding the reordering constraints of volatile)?

How does one write code that best utilizes the CPU cache to improve performance?
...
The cache is there to reduce the number of times the CPU would stall waiting for a memory request to be fulfilled (avoiding the memory latency), and as a second effect, possibly to reduce the overall amount of data that needs to be transfered (preserving memory bandwidth).
