Google Cloud Functions: Cold Start Duration per Instance Size
Google Cloud Functions have a setting to define the memory size that gets allocated to a single instance of a function. The CPU resources are allocated proportionally to the memory. So, in theory, larger instances could start faster.
However, there seems to be no significant speed-up of the cold start as the instance size grows.
All of the charts shows an advantage of larger instance sizes for cold starts, and the difference increases with the size of a deployment package.
