GraalVM CE does not support PGO(profile-guided optimization), so the native binary only reduced startup time and memory footprints without C1/C2 compilation as in JIT. Would be interesting if someone with GraalVM EE to fine-tune the configuration and share the test results.
Note: upx reduced the binary file from 32.7MB to 10.8MB, without performance degradation.
