> On the server side, this lets you use java which is a lot more performant than javascript is.

Is it? http://benchmarksgame.alioth.debian.org/u64/javascript.html

Yep: https://www.techempower.com/benchmarks/

Its also fairly obvious that a statically typed / compiled language will have better performance than an interpreted language. Compiler optimizations make a huge difference as well.

Also, even the link you gave shows js being slightly faster in 2 or 3 benchmarks, but for the remaining 4-5, java is significantly faster.
