          <li><strong>Lower memory consumption:</strong> By minimizing allocations and class loading, Quarkus reduces memory usage. Replacing reflection with build-time bytecode generation further lowers the JVM's runtime workload.</li>
          <li><strong>Better latency and improved throughput:</strong> Quarkus generates highly optimized code at build time and prunes unnecessary classes and methods. For instance, it weaves layers of indirection together, enabling better JIT optimizations. These improvements result in faster code and better latency. </li>
