Advanced Linux Kernel Bypass Techniques in 2023

This asynchronous interface brings substantial performance improvements to databases and networking applications, but is still rarely seen in real products. Still, even that is not State-of-the-Art. We will talk about SPDK, DPDK, and the kind of performance you can expect from high-end SSDs and 200 GBit Infiniband.
