Appsync, Serverless Lambda, RDS (aurora postgresql) API response taking more time (avg. 1.5sec)

0

Each appsync query/mutation taking more time to response. Average API response time is 1.5sec. Even static text returning from lambda also taking reponse time around 700ms. I've tryed with enable caching in Appsync. Can you please suggest to me how can I improve response time ?

Hi,

Firstly, we need to find which part occupied the most long time. Have you checked the duration of Lambda?
You can check the aws lambda cloud watch log and observe the report[1].
You should see the following output:

START RequestId: 57f231fb-1730-4395-85cb-4f71bd2b87b8 Version: $LATEST

END RequestId: 57f231fb-1730-4395-85cb-4f71bd2b87b8

You can check the Duration and Memory Size and Max Memory Used to determine whether to increase your lambda memory.
