New Mars storyboard
An Urbit runtime with near-machine execution speed and NAS-equivalent addressable storage enables most classes of personal applications to be built directly on Urbit.
Near-machine execution speed
Currently standard library functions which implement highly-iterated loops, such as
turn, are jetted to remove arm invocation overhead arising from indirect jumps, dynamic jet matching, and allocation for parameters. The majority of overhead in hot codepaths (such as Ames) is in arm invocations themselves, not in the code for arms.
