The performance optimization and tuning skills of the Jetty framework in the Java class library

Performance optimization and adjustment skills of JAVA Library Jetty framework The Jetty framework is a lightweight Java Web server with excellent performance and scalability.However, performance optimization and tuning are still very important when dealing with high and large loads.This article will introduce some performance optimization and tuning skills for the Jetty framework to improve its performance and efficiency. 1. Use the latest version of the Jetty framework: Make sure you use the latest version of the Jetty framework, because the new version usually fixes some performance problems and introduces new optimization.Check the official website of Jetty to get the latest version. 2. Adjust the thread pool size: Jetty uses a thread pool to process the requests that pass in.According to your application requirements and expected loads, adjust the size of the thread pool to ensure that sufficient threads can be used to process requests.You can change the size of the thread pool by configure the `ThreadPool` of Jetty. Example code: Server server = new Server(); QueuedThreadPool threadPool = new QueuedThreadPool(); ThreadPool.setmaxThreads (200); // Set the maximum number of threads of the thread pool server.setThreadPool(threadPool); 3. Enable compression: Enable GZIP compression can reduce the amount of data transmitted, thereby improving performance.The compression function can be enabled by adding the following configuration to the configuration file of Jetty: <Get name="gzip"> <Set name="inflateBufferSize">8192</Set> <Set name="minGzipSize">2048</Set> </Get> <Set name="connectorType">nio</Set> Example code: Server server = new Server(); ServerConnector connector = new ServerConnector(server); HttpConnectionFactory httpConnectionFactory = connector.getDefaultConnectionFactory(); httpconnectionFactory.gethttpconfiguration (). SetoutPutbuffersize (8192); // Set output buffer size httpconnectionFactory.gethttpconfiguration (). SetRequestHeadersize (8192); // Set the request head buffer size httpconnectionFactory.gethttpconfiguration (). SetResponseheadersize (8192); // Set the size of the response head buffer area size server.setConnectors(new Connector[] { connector }); 6. Use the cache: Enable the appropriate cache to reduce the request of the back -end server and improve performance.You can use the `Resourcehandler` in Jetty to enable the static resource cache. Example code: Server server = new Server(); ResourceHandler resourceHandler = new ResourceHandler(); resourceHandler.setDirectoriesListed(false); resourceHandler.setWelcomeFiles(new String[]{ "index.html" }); ResourceCache cache = new ResourceCache(); cache.setCacheControl("max-age=3600"); resourceHandler.setCache(cache); server.setHandler(resourceHandler); 7. Establish a pre -compilation page: Jetty supports performance through pre -compilation JSP pages.You can use the page pre -compilation in the configuration file of Jetty. <Set name="development">false</Set> 8. Use appropriate garbage recycling configuration: Appropriate garbage recovery configuration can help reduce the pause of the application and improve performance.You can configure garbage recovery by setting appropriate JVM parameters when starting Jetty. Example code: shell java -Xms1G -Xmx1G -XX:+UseG1GC -XX:+UseStringDeduplication -jar jetty.jar The above are some optimization and optimization skills to improve the performance of the Jetty framework.According to the needs and load features of the application, you can make appropriate adjustments and optimization as needed to obtain the best performance and efficiency.Remember to carry out the benchmark test to verify that any changes have a positive impact on performance.
