Please explain ! What has reflection to do with v-tables and selector
hash lookups ?

You mean dynamic invocation is slower ? This is certainly implementation
dependend, eg there is nothing which prevents using the same method
invocation mechanism in a JVM (that is, mapping functions to selectors).
No one forces you to use vtables in JVMs.
