The other major unsolved issue is multi-socket scaling. As it turns out, attempting to scale a single VM across multiple sockets is extremely inefficient with current software, resulting in tremendous drops in throughput as soon as the first thread migrates to a second socket. The current workaround is to give the VMs socket affinity and to run one VM per socket, but nobody is satisfied with this.
What does 'socket' refer to, in this context? A network socket? A CPU socket (not to be confused with cores)? Some database-specific term I'm not familiar with?

I read it as CPU/Core

It refers to a CPU socket. Basic NUMA scaling issues, really.
