Python layer:

Compressed:
Current size: 5MB
Building with aws-encryption-sdk + cryptography: 9-10MB

Uncompressed
Current size: 12MB
Building with aws-encryption-sdk + cryptography: ~ 29MB

We have little difference in ColdStart using the layer with and without aws-encryption-sdk, just few ms, even importing the AWSEncryptionSDKProvider + DataMasking. But of course, the first execution of encrypt or decrypt takes 3x times than the second using the same Lambda. Most of this time is calling KMS + Creating cache + caching python libraries.

Executions:

First encrypt execution (coldstart) - 128MB - 3.5s
Second and subsequent encryption executions (warm) - 128MB - 1.0s (edited)

First encrypt execution (coldstart) - 1024MB - 450ms
Second and subsequent encryption executions (warm) - 1024MB - 140ms (edited)
