Today we are going to discuss with you the basic test of two MySQL performance items. I saw the basic test materials for two MySQL performance items on a reputable website two days ago, I think it's good. I just want to share it with you. I hope you will have a deeper impression after browsing. The following articles m

This article supplements the "Bullet HashMap memory compact hash Table" debt owed (hereinafter referred to as "Bthashmap")."Bthashmap" is a theoretical analysis of the bullet hash map (BTHASHMAP) and C + + standard library hash map (STD::UNORDERED_MAP) memory layout. Bthashmap and Std::unordered_map, like most dictionary of voice environments, are designed to be dynamically grown containers; I asserted in bthashmap that when size is small, bthashmap is relatively std::unordered_ Map has better

compiler, recommend GCC more than 4.8, because only gcc more than 4.8 PHP will open the Global Register for Opline and execute_data support, this will bring about 5% performance improvement. So the GCC version selected for this experiment is GCC versions 4.8.2 20131212 (Red Hat 4.8.2-8) (GCC). After installation, do the soft link: Ln-s/usr/local/php7/bin/php/usr/bin/php7 ln-s/usr/local/php7/bin/php-config/usr/bin/php7-config ln-s/ Usr/local

There is nothing worse than this, the adoption of a new application, and its performance is so bad, leading to business in a scream of pause. This is not a new phenomenon; it is the fact that I have often encountered such a fact. I bet you've been there before. So how do you prevent these performance problems and what are the solutions? In cases where these applications are "paused in the Scream", the appl

Apache JMeter is an open-source performance testing tool that is written in Java and can be used for performance testing. JMeter was originally designed for web application testing and was later extended to multiple test areas.Apache JMeter can be used for static resources and dynamic resources (including webservices (soap/rest), Dynamic Web languages (PHP, Java,

Tags: OSD development disk HTTP MySQL service res fill command lineMysqlslapThe MYSQLSLAP can simulate the load on the server and output timing information. It is included in the MySQL 5.1 release package and should be available in MySQL 4.1 or later. The number of concurrent connections can be executed at test time, and the SQL statement can be specified (either on the command line or in the parameter file). If no SQL statement is specified, Mysqlsla

Performance testing result analysis is the top priority of performance testing. In actual work, the analysis of the test results is complex. Complex and requires a lot of relevant professional knowledge, so I often feel that I don't know where to get the data. This is also my learning performance I felt awkward and dif
