Hi Adam!

What approach would you recommend to improve the performance of a AWS serverless REST API current services used are Route53, rest API Gateway (with private VPC), Lambda and RDS (on the same private VPC).

The service takes about 11sec to start what it means is because of the timeout of 10sec of a Lambda it takes 21sec.
I already tried to remove Liquibase (and it improved 2/3 seconds) and changed the architecture to x86 and it also improved 1/2 sec so now the startup sometimes is bellow 10 secs, but its not consistent.

The project is very similar to your plain examples with Java and Quarkus.

Thanks in advance!
