Is a 100ms startup time really a big deal for something that is either going to be manually triggered or cronjobbed and expected to take on the order of minutes?
Ruby scripting has occupied the sysadmin space for over a decade yet on my 2013 Macbook Pro the latest Ruby 2.6.5 takes around 250ms to start. That's a mere 1/4 of a second. Sure, Python, Perl and PHP have shorter startup times but surely this is a non-problem?
