Shouldn't this be "io_uring is faster than mmap"?

I guess that would not get much engagement though!

That said, cool write up and experiment.

Its not even about clickbait for me, but I really dont want to go parse an article to figure out what is meant by "Memory is slow, Disk is fast". You want "clickbait" to make people click and think, we want descriptive tittles to know what the article is about before we read it. That used to be original purpose of tittles, we like it that way.

Its like as if youd label your food product "you wont believe this", and forced customers to figure what it is from ingredients list.

I get that. But I do actually show a scenario where accessing data from memory using a very standard mechanism IS slower than a newer but equally standard way of accessing data from an NVMe drive.

"Accessing memory is slower in some circumstances than direct disk access"
