Io_uring and EBPF Will Revolutionize Programming in Linux

"As devices get extremely fast, interrupt-driven work is no longer as efficient as polling for completions — a common theme that underlies the architecture of performance-oriented I/O systems"

Uniquitous SMT also makes polling more palatable. The current x86 SMT is still of the minimalistic sort with only 2 threads per core, this kind of programming pattern might be a reason for more HW threads?

Thanks, a very well written article!

We are doing research on Very Large Base Interferometry over the network (eVLBI) for radio telescopes across several countries to synchronise big data from astronomical observatories. The new techniques mentioned in the article potentially can really speed up the process for storage, networking and synchronisation.
