and will cause a lot of memory fragmentation, the related parameter setting will be introduced later.Make reasonable use of query cacheWith the pros and cons of query cache, using query cache wisely can make it an advantage and effectively avoid its disadvantages.1. Not all tables are suitable for use with query cache. The reason why the query cache is invalidated is that the corresponding table has changed, so you should avoid using query cache on a table that is changing frequently. There are

This article describes how to use an optimizer to improve the execution efficiency of Python programs, including writing timers and using built-in Optimizer, if you need a friend, it is unwise to start optimization without first thinking about the famous saying of Knuth. However, you can quickly write code that adds some features, which may be ugly. you need to pay attention to it. This article is prepared

In Apach, Zend Optimizer and Xdebug are loaded with dynamic libraries through zend_extension_ts; Then if you use Zend Optimizer and xdebug at the same time will be error; Then find a way to copy Php_xdebug-2.1.2-5.2-vc6.dll to ext, with the following method to solve, but still not normal loading xdebug; So I want to ask you how to solve the great God!!

The MySQL query optimizer has several goals, but the primary goal is to use the index as much as possible, and use the most restrictive indexes to eliminate as many rows of data as possible.Your ultimate goal is to submit a SELECT statement to find rows of data instead of excluding rows of data. The reason the optimizer tries to exclude rows of data is that the faster it excludes rows of data, the faster it

Zend Optimizer (ZO) uses code optimization methods to speed up the execution of PHP 4.0 applications. The principle of implementation is to optimize the code generated by the Run-Time Compiler before it is finally executed. Optimization can improve your profitabilityGenerally, PHP programs that use ZO are 40% to 100% faster than those that do not use ZO. This means that the visitor of the website can browse the webpage faster, so as to complete more t

MySQL has provided the optimizer Option Switch option since 5.1. In this way, we can force some things that we think should not be done when the optimizer is confused, or when we want to see why the optimizer is so selective, you can manually disable or enable these options to change the optimization policy.In MySQL 5.1, the following switch is added:MySQL 5.5 ad

Solve the problem related to the Optimizer in the MySQL database. MySQL uses an overhead-based optimizer to determine the optimal solution for processing queries. In many cases, MySQL can calculate the best possible query plan, but in some cases, MySQL does not have enough information about the data and has to make a "educated" estimation of the data. When MySQL fails to do "correct", you can use the fol

By now, Zend optimizer's current versions are 3.3.3 (Windows) and 3.3.9 (Linux), and php5.3 and later versions are not supported. Many of my colleagues, including myself, have always been able to use php5.2 only by B. Of course, because Dede has poor support for php5.3, there is no way to stop at the 5.2 era. According to the official statement, this has always been the case: due to too many upgrades to php5.3, after ZP is updated, it will no longer be compatible with PHP files encrypted by Zeng
