Hi, we are running a spring-boot app as graal native binary. We experience bad database connection performance during high load phases. In the below graph you can see the number of open connections. Red lines are legacy Java VM instances. Blue lines are graal native canary instances:
Database communication is much slower with graal native, which causes a huge number of open connections during high load, since connections are not returned fast enough.
We are already optimizing it by recording a pgo profile on production and using G1 gc.
Any hints why database performence is slow with graal binary?
Best regards
