So a statically typed compiled language is quicker than Ruby... Not exactly shocking. Ruby's advantage isn't in its speed, but in how easy and quick it is to get things done.
Statically-typed and speed aren't necessarily correlated. If you want a framework faster than Go, dynamically-typed and rivaling Ruby's development speed, have a look at OpenResty+Lua+LuaJit (And MoonScript if you really want to code fast).
