+       <p>Quarkus redefines how Java applications are built and executed by shifting much of the work to the build phase ensuring that the costly work happens only once — during the build process — not at every startup. It results in faster, smaller, and more resource-efficient Java applications on both GraalVM native images and traditional JVM deployments.</p>
+       <p>For example, at build time, Quarkus reads part of the application configuration, scans the classpath for annotated classes, and constructs a model of the application. By doing this early, Quarkus has enough information to eliminate unnecessary components and compute the exact startup instructions required.</p>

+         <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>

+      <p>Quarkus is built on reactive principles, using an efficient asynchronous, non-blocking engine based on Netty and Eclipse Vert.x. It employs a few event loops instead of a large thread pool, reducing resource usage and improving response times by optimizing for hardware behavior.</p>

+      <ol>
+        <li><strong>Imperative model:</strong> A traditional synchronous approach with faster execution due to an optimized I/O layer, ideal for lower concurrency. High concurrency increases memory use.</li>
+        <li><strong>Reactive model:</strong> Enables high concurrency with minimal resources using asynchronous, non-blocking code, but is more complex to implement and debug.</li>
+        <li><strong>Virtual threads (JDK 21+):</strong> Combines the benefits of imperative and reactive models, allowing imperative code to run on lightweight virtual threads for high concurrency with low memory overhead, though some limitations remain.</li>

The reactive core further cuts memory usage by using a few event loops instead of a large thread pool, allowing the application to handle higher loads with a smaller memory footprint and enabling high deployment density.</p>

+        <h3>Fast Startup Time</h3>
+        <p>Thanks to the build-time optimizations, most of the application’s heavy lifting, such as classpath scanning, configuration loading, and dependency injection setup, happens before the application even starts. This significantly reduces the time it takes to get the application up and ready to serve. The reactive core contributes to this by ensuring that I/O operations are handled with minimal blocking, further reducing the startup latency.  The efficient startup process means the application can respond to new load conditions more quickly. This combination supports implementing  LightSwitchOps patterns,  enabling elasticity while controlling costs.</p>

The reactive core minimizes blocking in I/O operations, further lowering latency and allowing handling a large number of concurrent tasks. </p>
