Introduction to Magento Optimization

This document describes how to use Oracle Service Bus and Oracle Coherence caching capabilities to improve performance of a slow web service. It shows how to create a sample web service that takes 9 seconds to respond using Java and deploy it to WebLogic Server. Then it imports the web service into an Oracle Service Bus project and enables caching for the business service. With caching enabled, subsequent requests return immediately from the cache instead of calling the backend web service. It also describes how to use an external Coherence server for out-of-process caching and monitoring the cache using the Coherence console.

This document summarizes a presentation given by Luxi Chidambaran of Oracle on solving the C20K problem of scaling PHP applications. It discusses how the Oracle 11g Database Resident Connection Pool (DRCP) allows PHP applications to connect to the database in a way that supports tens of thousands of concurrent connections using minimal system resources. It provides an overview of DRCP and how the enhanced OCI8 PHP extension connects to leverage DRCP. Performance benchmarks are presented showing significant increases in throughput and reductions in memory usage compared to non-DRCP connections.

This code is not thread-safe because the idNum field is being incremented without synchronization. If this JSP page was accessed concurrently by multiple requests, it could generate non-unique IDs by incrementing idNum multiple times between requests. To make it thread-safe, the idNum field would need to be declared as volatile or access to it would need to be synchronized.

This document provides an overview of state management in ASP.NET, including client-based state using view state, cookies, and query strings, as well as server-based state using application state, session state, and profile properties. It discusses when each state management technique is appropriate and how to implement them in ASP.NET applications.

This document provides tips for improving the performance of ColdFusion applications, including writing code in an object-oriented style, checking for errors first and planning fast exits, limiting nested loops, knowing which ColdFusion functions to avoid, testing execution speed, using stored procedures, caching pages, queries and ORM data, and flushing caches when needed. Additional resources are provided on optimizing ColdFusion applications and performance tuning servers.

Servers - Apache Tomcat Server Server-side scripts - Java Server Pages The document discusses request/response protocols for client-side scripts versus server-side scripts like Java Server Pages. It explains how a server can interact with multiple concurrent clients through multi-threaded responses. HTML meta-tags can control the request/response interaction, and the file extension (.html vs .jsp) affects how the page is processed.

The document discusses various techniques for building mashups including AJAX. It defines mashups as lightweight web applications that combine content from existing sources via public APIs. It describes how AJAX uses XMLHttpRequest to asynchronously retrieve data from servers in the background without page refreshes. This improves responsiveness. JSON is also discussed as a data format used for mashups. Challenges with mashups include lack of APIs and difficulties accessing unstructured internal data.

This document discusses tuning web performance from a frontend perspective. It covers the impact of performance on user experience, development tools for optimization like Firebug and Chrome DevTools, and various techniques for website optimization including reducing requests, optimizing images, leveraging caching, minimizing JavaScript, and improving loading efficiency.

It also discusses tools like LoadRunner, Controller, and Analysis for executing and analyzing tests. The document emphasizes having a thorough test process and communication plan to ensure performance testing is done correctly.

ASP.NET uses an event-based programming model where event handlers are executed in response to events. Events can be page events, which always occur, or control events associated with specific controls. When a browser requests an ASP.NET page, the page class is dynamically compiled and executed on the server to produce the HTML and JavaScript sent to the browser.

This document provides an introduction and tutorial for JavaServer Pages (JSP) technology. It explains how to create simple JSP applications that handle HTML forms and pass data between the client and a JavaBeans component on the server. Examples are provided to demonstrate creating a basic "Hello World" application, handling form submission and passing user-entered data to a bean using JSP tags, and writing the corresponding JavaBeans component. The tutorial also explains how to install and run the example applications using Tomcat.

The document discusses the implications of overfishing in oceans and the Chesapeake Bay. It notes that overfishing is threatening marine life by taking fish out of bodies of water faster than populations can be replenished. This can disrupt food chains and ecosystems. In oceans, overfishing endangers species like sharks that regulate other marine populations. In the Chesapeake Bay, overfishing has reduced the oyster population to 0.3% of historic levels, worsening water quality since oysters filter contaminants. Overall, overfishing in oceans and the Bay poses serious threats to marine life, ecosystems, and ultimately humans who rely on healthy waterways.

Shafia Begum and Mia worked on completing the sound for a film trailer over several sessions from March 16th to March 16th. They used GarageBand to add background music and sound effects. Mia recorded additional voiceover and they edited the narration to fit each scene. Their final session involved some additional editing touches and adding a "Double Take" sound effect to a shot at the end of the trailer. Through this process, they learned how to structure voiceovers and adjust audio levels to balance music and dialogue.

This document discusses the history and research on summer school programs in the United States. It notes that summer school was originally used for recreation but began focusing on remediation in the 1950s. Research shows disadvantaged students experience greater learning loss over the summer. Recent increased emphasis on standardized testing and promotion standards has led more districts to use mandated summer school, but research on its effectiveness has been limited until a 2000 meta-analysis of 93 program evaluations.
