How does Foreign Function & Memory API (Panama) impact performance or memory usage?

The Foreign Function & Memory API (Panama) provides several enhancements that can significantly impact performance and memory usage in Java applications. By allowing Java to interact directly with native code and manage memory more efficiently, Panama reduces the overhead and latency associated with traditional JNI (Java Native Interface) calls.
