Cold start time and package size too high

[Dizzzmas]

Problem

Lambda cold start with this setup takes around 1ms which seems to be a bit too high, considering that if used with RDS and an ORM it would probably go even higher. Also, the package size is around 6MB which is sub-optimal.

I'd love to see these issues addressed or at least some help with how to get on track towards solving them.

What I tried

serverless-plugin-optimize and serverless-plugin-webpack

This has resulted in the following error:

    "errorMessage": "Unable to find package.json in any of:\n[/var/task/_optimize/serverless-graphql-dev-graphql,\n/var/task]",
