6 - Octave now has an experimental virtual machine (VM) for just-in-time (JIT)
7 compilation of m-code. This VM can be enabled by the end user with the
8 command `__enable_vm_eval__ (1)` as long as the configuration option
9 `--disable-vm-evaluator` was *not* used when building Octave. Speedups from 2X
10 to 40X have been observed for different kinds of m-code. This feature is
11 considered experimental for now. M-code that cannot be handled by the VM yet
12 falls back automatically to the existing interpreter.
