Lambda

There is a performance degradation after adding the layer to AWS Lambda

The Dynatrace layers may require a minimum amount of memory, it is documented for Java, see the Dynatrace documentation here and the notes on the README.

Make sure you are using the latest versions of the VPC stack and SAM Deployment Pipeline as per the Prerequisites. In case we have fallen behind in keeping the versions up to date in the readme you can also check the di-devplatform-deploy repository tags for yourself.
