Perhaps you could factor in something about cold-start?
I know that in my context, this has been a key issue. Another odd one is that our organization has only certified RHEL and Cent OS running server-side code.
What exactly are your issues with cold start? This typically only affects functions that are called a few times a day, and can be solved for those functions by running a CloudWatch event that triggers your function every few minutes or so. You get 1 million free invocations a month, so this typically doesn't increase your bill.
We have code that you can run on your AWS account for more accurate information from servers.lol based on Cloudwatch metrics. Latency and coldstart information would be totally interesting, I'll suggest it to our team!
