Close to viable. The breakdown shows the levers worth pulling.
Valkey 9.1 brings a novel functionality: pluggable lua-engines. Default one is lua 5.1 which is slow and unsupported for many years. This is why we tried to bring in luajit. It's mostly lua 5.1 compatible and gives about x2-x5 performance boost on common workloads. Module is replacing the built-in lua by default or optionally lives right along with it.
