I think you are confusing the Just In Time compilation technology used to
convert heavily used routines to faster executing forms with the initial
compilation from source to byte code. Since the program is executing during
the JIT compilation phase, there is no delay for the user.

Further, if instead of using a KVM, the processor is designed to execute
byte code directly, then the byte code is the native format and there will
be no penalty for byte code execution at all. (Though in truth the current
VMs plus JIT compilers are already fast enough for most real applications.)
