The proxies had to satisfy three constraints:
While Gelidium seaweeds can be collected by gathering fragments washed ashore, mass production of agar requires steady, large quantities.10 Harvesters in New Zealand during WWII had to “walk beside a boat, waist to armpit deep in water and feel for the weed with their feet.” Handling large volumes of wet seaweed (which yields less than five percent agar) was challenging. Then as now, when Gelidium is harvested by scuba divers from rocky seabeds, collectors have to understand the life cycle of the algae, find the most likely locations for its growth, and prevent overharvesting to safeguard future yields.

The last step is executing the writes. This is achieved through copy_to_user_page(), which is essentially a memcpy. Since the destination is the writable mapping from kmap(), this just works.
In the 2024 comparison Intel Emerald Rapids did quite well, but it turns out that is only on non-busy nodes, where the cpu allows for a generous boost - at least for GCP. This is reflected as the range you see on the graph. The new Granite Rapids seems to fix this, providing a bit higher, but mainly more stable performance. So, a solid step forward from Intel, it's just that Turin is really impressive.
