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 management? IIS6.0's application pool automatic recycle funct

, and most of the business logic also occurs in these events, so the processing of such events requires more CPU. In this case, the pressure on the front-end server is mainly I/O, and the pressure on the Scenario Server is mainly on the CPU. If the pressure on the front-end server is deployed separately on different machines, the pressure on the servers on both sides is not balanced. The front-end servers have a lot of CPU remaining, and the CPU of the server is insufficient in the scenario. So

Nginx is very suitable for web sites because it is small and occupies less resources. More and more Linux + nginx + PHP + MySQL sites have gradually surpassed Apache and Lighttpd in recent years. If Google-perftools developed by Googler is used to optimize the memory management of nginx and MySQL, the performance will be improved to a certain extent. especially for servers with high concurrency, the effect is more obvious. this tutorial is applicable

Method 1: Define the appropriate referential integrity constraints between the fact table and the three dimension tables In DB2, you can define primary key and foreign key constraints to allow the database manager to enforce referential integrity constraints on the data. Referential constraints such as foreign keys also help improve performance. For example, if you modify the subexpression TMP1 in the query in Listing

Create a notification Handler Now you can create a notification handler, which will use the sendNotificationThe process sends a change notification to the client. Let's take a look at the PL/SQL process orders_nf_callback in Listing 2.List 2.Notification handler that processes changes to the OE. ORDERS table CREATE OR REPLACE PROCEDURE orders_nf_callback (ntfnds IN SYS.CHNF$_DESC) IS tblname VARCHAR2(60); n

Ec (2); after php5, the _ autoload interceptor method is introduced to automatically include and reference class files. We usually write this: copy the Code as follows: function _ autoload ($ classname) {include_once $ classname .. class. php;} $ usernewuser (); when the php engine attempts to instantiate an operation of an unknown class, it calls script ec (2); script After php5, the _ autoload intercep

This article describes the problems that need to be paid attention to when deploying Memcached and the distributed algorithms of Memcached, whether you are a new system or a system that has been online for a long time. We can easily configure Memcached, but before we configure it, we need to pay attention to the following issues: 1. memca this article will introduce the problems that need to be paid attention to when deploying Memcached and the distributed Memcached algorithm. Whether you are a

Problem: The project uses Ajax technology. Some requests have a large number of parameters, mainly coordinate pairs. For cross-origin access, jsonp is used, but get is used for sending requests, the length of the request is limited. When a browser processes a request that exceeds the maximum limit, it divides the request into two parts, which is equivalent to sending two requests. LoadRunner faithfully records these two requests as two web_urls during recording. The recorded script is as follows
