IIS6.0 Application pool recycling and worker processes A company's web site program after a long run, slow speed, restart the site after the speed significantly faster, estimated that the Web site program occupied by the memory and CPU resources can not be released in time, only need to restart the site every time the release of resources. But manual restart is not the solution to the problem, how to achieve automatic

1. cache OverviewCache is a set of examples in memory in java applications. It stores backups of data from permanent storage sources (such as files or databases on hard disks, it reads and writes faster than hard disks. The application reads and writes data in the cache directly at runtime, and updates the data storage source synchronously only according to the data in the cache at certain times. If the volume of data stored in the cache is very large

State management of long-time data (such as cursors. You cannot tolerate lag or pause when an operation is being processed by your application. If an operation is time-consuming and resource-consuming, You need to detach the operation and perform asynchronous processing on it, so that your application remains responsive and users can process their transactions.

The reactor development model is chosen by most high-performance servers, and the IO multiplexing described in the previous article is the basis for its implementation. Timing triggering is usually a server prerequisite, and the reactor model often has to include the management of the timer. This article will introduce the characteristics and usage of the reactor model. First we need to talk about why the n

(3) it is an internal LAN, includes intranet web servers, backend database servers, and OA servers. (4) VOD private network, including audio and video on-Demand Servers. Due to the establishment of strict network-level and application-level access permissions, through a high-

that we can master some of the principles of the framework, presumably the significance of the application of tuning is very significant, today, mainly to talk about. Assuming there is no picture loading frame, how do we deal with Bitmap's memory problem?When it comes to bitmap, we may want to start with some basic knowledge about bitmap memory allocations in Android virtual machines and give the following paragraph on Google's siteThe general meanin

Although Android smartphones and tablets are faster than a day, developers must remember that their applications are still running in a resource-intensive environment, this environment relies primarily on batteries and processors that are unmatched by the latest desktop or laptop. Some of the methods described below can help your applications to "slim down" or "Ten Key Points for Android to improve development performance" so that they can run smoothl

You need to design your performance in advance, or rewrite your

IIS6.0 application pool collection and workflow After a company's website program runs for a long time, the speed slows down and becomes faster after the website is restarted. It is estimated that the memory and CPU resources occupied by the website program are not released in time, you need to restart the website to release resources at intervals. However, manual restart does not always solve the problem. How can we achieve automatic

local management" philosophy also extends to the deployment of ASP. NET Framework applications. You only need to copy the necessary files to the server to deploy the ASP. NET Framework application to the server. You do not need to restart the server, even when you deploy or replace the Running code. Scalability and availability. ASP. NET has been designed with Scalability considerations and added a feature

authorize other users with the permissions that they own, usually with the following: With GRANT option to achieve the purpose of authorization.9, we can grant all available permissions for a level to a user through the grant all statement:Grant all on TEST.T4 to ' ABC ';Note: The above five permissions: Table,column,routine the objects that are dependent upon authorization must be present, unlike database level, which can be authorized when the current database does not exist.4.2.4 access Cont
