AWS rest api with blank Lambda - First response too slow

When API Gateway calls a blank Lambda function, the first response time is 1500ms.

The following response time is 150ms.

Is that normal or is something is wrong?

This is due to Lambda cold start which is normal/expected behaviuor. There are various ways you can improve the cold start

  • Try with a larger memory allocation (note that Lambda cost is proportional to memory and cpu)
  • Try provisioned concurrency
