That is very neat! I always thought about expanding that idea to most programming languages. Most of the startup time is probably spend stating and reading files. Just from a quick experiment time python -c ''; time python -S -c '' real 0m0.079s user 0m0.021s sys 0m0.030s real 0m0.017s user 0m0.007s sys 0m0.007s From the manpage: -S Disable the import of the module site and the site-dependent manipulations of sys.path that it entails. I also considered doing the same thing for a linux distro. Just out of pure curiousity to what would happen to the boot up times. Wish I could have time to try it one day :(

What about going all the way and using an unikernel (or something approaching one)? Statically link suitable readonly data/code into a single global address space (to make use of optimizations possible by combining binaries, as apparent in e.g. busybox, and remove the overhead of code duplication and dynamic linking, if possible even skipping some overhead with syscalls, by allowing the compiler to reduce spilling registers to stack in an effort to prevent clobbering), and just make sensitive and modifiable data unavailable to or at least not writable by other/unprivileged processes. This would probably require some modification to GCC or LLVM, if the latter even supports building a normal Linux.

  Madness! Or actually really similar to an idea that Joe Armstrong presented in Strange Loop one time (just the idea no demo or anything) https://www.youtube.com/watch?v=lKXe3HUG2l4 https://www.youtube.com/watch?v=lKXe3HUG2l4

    There exists an Erlang unikernel (of sorts): http://erlangonxen.org/ http://erlangonxen.org/

      Well yeah, but that's like saying there exists hardware that eats java bytecode. Yes, it does, but it brings _large_ restrictions with it.

https://github.com/regularfry/carton https://github.com/regularfry/carton is where I got to. Might give someone some ideas.
