Hi Sven, I'm curious how you are running your image.
I am following this tutorial -
https://aws.amazon.com/blogs/compute/scripting-languages-for-aws-lambda-running-php-ruby-and-go/
And am running pharo like the GO example by exec'ing via node js.
My aim was to write an Alexa service in pharo vs nodejs like I have been doing.
I was assuming I can call pharo via the eval option and stringify the Jaon
Alexa Paramus and return a result via Stdout... well in theory, and the work to
make pharo play better in wider ecosystem.
It should work, and it seems you did make it work... but how?
Like you, I am wondering when I run it on an ec2 instance (non lambda), why it
takes so long to load? It feels like it can be faster?
