You've probably heard of Google Web Toolkit (GWT), which supports writing Web applications in the Java™ programming language, and then compiling the Web application into JavaScript to run in a Web browser. This allows for increased productivity through the use of excellent t

Guidance:As a developer, the speed of loading or Refreshing Web pages is critical to their websites. Adjust performance problems in the browser than in Java applicationsProgramIs more difficult. There are much less methods for developers to debug Javascript in various browsers. For example, in Mozilla Firefox, you can use firebug to debug JavaScript, but still cannot adjust many

Wright's blog Python and Uwsgi with NGINX.ConclusionIn this section, this article describes a solution to improve the performance of a single server boost Python application that can be configured on a single server or on a reverse proxy server or a separate cache server. (The cache runs better on a separate

at the problems identified earlier and take measures. It may be that the system maintainer adjusts the collection load to make the load more uniform, or adjusts the host or database parameters, but more likely the program needs to be optimized by 4. Evaluate optimization effects such as the second example above, after taking the optimization measures, whether the network connection number or the database host load, has been very smooth, and the problem is no longer present.If not, repeat the ab

ObjectiveThe promotion of WEB 2.0 applications brings a whole new experience to the user, while also giving developers more attention to client performance issues. Recently, one of the founders of Dynatrace , a veteran Web Performance diagnostic expert and well-known tool , Andreas grabner According to their work expe

You can see URLs (links) and sizes from the image below, and AJAX-mode programs do make the home page bigger. In our test, about 3 K is larger. This is not surprising, because this page contains

Program | index | performance You can use SQL Server adjuster (SQL Server Profiler) tools to collect important information about the current activity of the server. The information tracked by this profiler tool, which contains the real load of the database, can be used on a variety of occasions. Now let's look at how to use Profiler to collect the data that can be used by the Index Tuning Wizard and how you can use these tools to debug your

Chrome developer tools Timeline and profiles improve Web application performanceSecond, reduce the number of HTTP requestsWhen a user browses to a page, if we load some information into the client cache at one time when the user first accesses, when the user accesses other pages, it can greatly improve the page access speed, because each time the HTTP request is to incur the server cost, the common method i

In the previous article, it was mentioned that the Nginx memcached module application scenario, mainly as a file cache. Then a problem is found, when large files are cached in a byte array, the cached data is compressed, which can cause problems when reading.(This article welcomes reprint, respect for others labor, reproduced please specify the Source: http://blog.csdn.net/poechant/article/details/7177603)The workaround is simply to set the compressio

to handle the client connection, and deletes the event when the client disconnects. Behind the scenes, Libevent handles network sockets, identifies the clients that need it, and calls the corresponding functions separately. To build this application, you need to compile the C source code and add the Libevent Library: $ gcc-o basic basic.c-levent. From the client's point of view, the server simply sends back any text sent to it (see Listing 3). Li

Through the research of the configuration and deployment of high-performance Web server Nginx-(11) Application module of the memcached module of the two major scenarios of the article, we know how Nginx read data from memcached, if hit, then the efficiency is quite high. So:1. What if I don't hit it?We can read the data to the appropriate data server and then cac

While keeping the code easy to understand and develop quickly. If performance is not a major concern, then a variety of different technologies can lead to very different speed differences.

For example, I must record the following information: (1) response speed during user registration, exceptions during registration, response speed during user logon, and exceptions during user logon; (2) under what conditions does the user attempt to download the free iopenworkssdk plug-in framework?

a groundbreaking JSP custom tag application that provides the ability to implement fast memory buffering within existing JSP pages. Although there are already some vendors providing various forms of caching products, they all belong to a specific vendor-oriented product. Oscache can be run on any JSP 1.1-compliant server, not only to buffer existing JSP blocks for all users, but also to buffer them in user units. Oscache also includes advanced featur
