For example, my friend worked in startup, based on Erlang. Once at public talk one guy asked "have you hear about Erjang, a virtual machine for Erlang, which runs on JVM, it is up to 5 times faster than Beam?". Answer was "5 times faster is not enough, to consider switch of platform, in my case, need 10 times faster".
