), Account_type=member (the type of freezing user), the parameters after Summary=xxxx is only for the convenience of logging and monitoring and incoming, and the actual business relationship is small. There are two commit functions listed here, with examples of two request methods to select the Commit function and how to convert the request to the LR code. The main thing is to understand what the captured data is, what to do with it, and what information each of the LR submission functions is fi

0.5 million users 2 webserver 1 Database Server when the number of users reaches 0.5 million, use 3 dbservers, one is responsible for receiving user submissions, and then copying to the other 2 databases, the other two copy user requests data with 1-2 million Vertical Split functions to multiple databases (one function is one database server) and then build a high-speed network between them. 3 million Although the system design is very independent, there are some copies that each database servic

Search process of HiPAC High-Performance Rule Matching AlgorithmWhen I received an email, A friend thought I had misunderstood nf-HiPAC. How can such a high-performance algorithm be forced by traditional hash and tree algorithms. Yes, HiPAC is a very powerful algorithm, and there are few documents. This increases the mystery of HiPAC, but it does not mean that it

First, glances:glances is a very good cross-platform performance monitoring tool that provides CPU, CPU queue, memory, virtual memory, network, I/O, and the list of processes that most occupy the server's resources.Indicator monitoring information, and at run time depending on the resource usage of different color labeling its importance, very intuitive, the following are in use:Second, glances installation:Glances installation is relatively simple an

for this phenomenon we can put the user's permissions in the session to reduce the number of connections to the database, thereby improving performanceThrough analysis we can find the most time-consuming method, the most time-consuming request URL, the most time-consuming SQL statement, through which we can easily find the program's performance short board, thus targeted to optimizeThree, memory analysisTo start the Memory analysis tool:Clicking the

the installation process for the VTune (intel® vtune™ Performance Analyzer) VTune makes it easy to optimize application performance through a graphical user interface without recompiling. --[Baidu Encyclopedia] Because of the need to use vtune analysis in a development project, the project that was developed is run in a Linux environment, so you want to install

ASP.net 2.0 contains a lot of secrets that, when you find it, can bring greater performance and extensibility to your program. For example, understanding the secret bottlenecks hidden in the membership and profile provider providers makes it easy to troubleshoot validation problems and make authorization operations faster. In addition, the ASP.net HTTP pipeline blocks to avoid the necessary code to execute on each request. Not only that, the ASP.net

Method of establishing process performance model Chi-Square test is a widely used hypothesis testing method, often used in the statistical inference of classification data, including: two rate or two composition ratio of the card-square test, a plurality of ratios or multiple composition ratios of the card test and the correlation analysis of the classification data. The chi-square test can test the con

Topics on the Python Application monitoring platform First of all, this is not a monitoring framework for everyone's business, I was in the last company, my department's monitoring framework ... When we first entered the field, the Nagios and cacti were used for monitoring. Two very powerful monitoring platform, scalability is also very good. If you want to use a platform to achieve alarm and performance information display, they both need to add so

All stems from an experiment, please see the following example: Table: Copy Code code as follows: CREATE TABLE IF not EXISTS ' foo ' ( ' A ' int (a) unsigned not NULL auto_increment, ' B ' int (a) unsigned not NULL, ' C ' varchar not NULL, PRIMARY KEY (' a '), KEY ' Bar ' (' B ', ' a ') ) Engine=innodb; CREATE TABLE IF not EXISTS ' Foo2 ' ( ' A ' int (a) unsigned not NULL auto_increment, ' B ' int (a) unsigned not NULL, ' C ' varchar not NULL, PRIMARY KE
