I am currently using AWS Lambda for my internal application to application calls using spring framework implemented with jrestless.
Application to application call is working perfect with decent latency(~10-15ms ideally)
But when I am trying to leverage same lambda function via API Gateway the latency shoots up to 700-800 ms. Even though my lambda function is taking same 10-15 ms.
Lambda Function Configurations:
VPC: open(no vpc)
Region: ap-south-1(Mumbai)
Memory: 1500 MB(Highest)
Timeout: 5 min(Highest)
API Gateway Configurations:
Region: ap-south-a(Mumbai)
Request Integration: proxy+
Request Method: ANY
No Authentication is being used and its an HTTPS call.
Has anyone faced a similar issue?
