In all the functions that are not webpacked, they all have the AWS SDK and XRay SDK in their deployment package (that’s how Serverless framework behaves). As you can see from the difference between them, the fact that the SDK is there doesn’t have any impact, it’s what you do with them — don’t require them, require only one client, or require the full SDK.

Memory might be a good one to look at, but I have another experiment for that. Hopefully will be wrapping it up soonish.
