The other funny bit is that one-way PCIe latency is 250ns-ish (don't quote me on the exact numbers), which imposes a hard 1us constraint on latency between two hosts.

You can go quicker with CXL, but not by much.

There are always DPUs like NextSilicon, NVidia's Blue*, etc - at under 100 ns of SoF to fast compute though.
