Native images are AOT optimized and use way less RAM than a normal Java app on HotSpot does. And you can get competitive performance from them with PGO.
Using a GC doesn't mean never reusing buffers, and Java has intrinsics for hardware accelerated cryptography for a long time. There's no reason performance has to be less, especially if you're willing to fund full time research projects to optimize it.
The belief that performance is more important than everything else is exactly how we ended up with pervasive memory safety vulns to begin with. Rust doesn't make it free, as you pay in developer hours.
