Hey Krishnan, I know very little about Ciro Santili's scripts, so I struggle to see what you're doing. I suspect in this example you are _just_ booting the kernel with literally nothing else (and possibly on the Atomic CPU?). This will be faster than a complete OS boot, but I normally run on the

Hi Bobby, Thank you for your response. You have mentioned that linux takes longer to boot. I just want to confirm if it is linux or ubuntu which is making the boot time longer. I just found a GitHub repo ( https://github.com/cirosantilli/linux-kernel-module-cheat) which uses buildroot instead of

Hey Krishnan, Linux does take about 45 minutes or so to run using AtomicSimpleCPU. You're not doing anything wrong in this regard. I'm afraid there's no information I can give you on making it faster. Anything to make this significantly faster, would be sacrificing the accuracy of simulation.
