-based relational database engine.The InnoDB storage engine is fully integrated with the MySQL server, and the InnoDB storage engine maintains its own buffer pool to cache data and indexes in main memory. InnoDB stores its table and index in a table space, a tablespace can contain several files (or raw disk partitions). This is different from the MyISAM table, such as in the MyISAM table where each table is in a separate file. The InnoDB table can be any size, even if the file size is limited to

reflect the impact of disk I/O on performance: The TERARKDB is written in an indexed and data-separated manner, enabling the writing of data to be converted to sequential write in some degree 2.2.3. Data is much larger than memory Operating system memory limit is 3G Set up a dedicated 256M cache for other databases 2.3.read-write Mixed TERARKDB is mainly used in a small number of read-write scenes A total

Web Report Software generally has three architectures. One is a pure Java report, one is a control method, and the other is a report software in the form of an independent server. 1. Control Mode: In this mode, an ActiveX control is installed on the browser. on the server side, only data is retrieved. Report calc

set, click the OK button to start the recording.First you will see the recording Bar, then will pop up IE and automatically jump to the set page, followed by the normal operation of the page function operation, and LR will convert the operation process into one submission request.4), insert commandYou can add some commands through recording bar during the recording process. such as slicing a script, adding the start and end points of a transaction, adding a collection point, adding a comment, a

Webpagetest was originally developed and used internally by AOL. Later, it was open-source on Google Code and is a very good browser performance testing tool. Online version http://www.webpagetest.org Google Code: http://code.google.com/p/webpagetest/ Deploy webpagetest private instance reference Http://testing.etao.com/node/303 Http://testing.etao.com/nodeThe client implementation

can be tested. The shortlist is frequently used because it is considered to have good performance in random insert and delete operations. Therefore, the following analysis focuses on the performance of the insert operation, that is, constructing a set. I tested and compared the rule list and ArrayList, because both are non-synchronous.The insert operation speed

1. Conclusion:The SAR command is a common tool for analyzing system performance on Linux systems, and can be used to view CPU, memory, disk IO, file read and write, system calls,2, the SAR will have a scheduled task, regularly record the current system information to/VAR/LOG/SA/XX, the default is to record every 10 minutes, when the SAR command does not specify the interval and number of times, is to display historical data.The SAR can also specify re
