I. BACKGROUND Recently, the company is doing some things networking products, object communication with the MQTT protocol, internal authority and internal relations and other business logic ready to use HTTP implementation. Leader requires a local test to simulate the need for millions of users to be online at the same time. Although the product does not necessarily have so many at the end, but since the request will be simulated. MQTT is using Erlang's Emqtt, a colleague who has tested millions

Significance and Calculation Method of Mysql database QPS and TPS The terms QPS and TPS are often mentioned in the monitoring of database performance. Next we will briefly share the meanings and calculation methods of QPS and TPS in the MySQL database. 1 TPS: the transaction volume per second. You can obtain the TPS value requested by the client

MySQL Key Performance Monitoring (QPS/TPS), qpstps Link: http://www.cnblogs.com/chenty/p/5191777.html During work, you may encounter various database performance tuning. In addition to viewing the execution duration of an SQL statement, you also need to have a better grasp of the overall processing capability of the system. QPS: Query per second, queries per second TPS: Transaction per second, Transacti

Andrew Morgan is the chief Product manager for Oracle MySQL. 　　 Recently, he wrote about how MySQL cluster supports the 200M QPS. about MySQL Cluster MySQL Cluster is a real-time extensible and acid-compliant transactional memory database. The database has up to 99.999% availability and low total cost of ownership of open source software. In terms of design, it employs a distributed, multi-master-node architecture that eliminates single points of

QPS query per second)Queries per second QPS is a measure of the traffic processed by a specific query server within the specified time. On the internet, the performance of machines serving as Domain Name System servers is often measured by the query rate per second. Terms:QPS = req/sec = number of requests/second [Method for Calculating PV and machines in QPS]

Terms: QPS = req/sec = number of requests/second [Method for Calculating PV and machines in QPS] QPS statistical method [http_load is generally used for Statistics]QPS = Total number of requests/(total number of processes * request time)QPS: Number of successful request

Term Description: QPS = REQ/SEC = Number of Requests/sec "The way the QPS calculates PV and machines" QPS statistics [general use of http_load statistics] QPS = Total Requests/(total number of processes * Request time) QPS: Number of successful requests per second of a s

After upgrading MySQL from 5.0.49 to 5.1.68, the QPS doubled; 650) this. width = 650; "src =" http://www.bkjia.com/uploads/allimg/131229/2111425108-0.png "title =" 1.png" alt = "155624252.png"/> After review the applications of all domains, the conclusion is that the QPS of the application is basically not changed. Where does this strange

On the Web server side, the daily traffic is huge. In a non-production environment, stress testing of the server is required, typically using a background thread and sleep mode to simulate the stress on the line. Here a simple QPS test code is implemented using Scheduledexecutorservice.Qpsproxy:Import Com.google.common.base.preconditions;import Org.apache.commons.lang3.math.numberutils;import Org.slf4j.logger;import Org.slf4j.loggerfactory;import Java

Reveal the secrets of increasing QPSGuideIn actual development, many people fear that the QPS of the system increases, because they think that the system will be suspended if the QPS is too high. Based on this mentality, they will try to reduce the system's request volume as much as possible, some people may even place a lot of processing in the service for processing. In this way, when an external request

will be required to start 20 threads. That is, starting 2 threads per second.Number of cycles : The number of times each thread sends a request. If the number of threads is 20 and the number of cycles is 100, then each thread sends 100 requests. The total number of requests is 20*100=2000. If "Forever" is checked, then all threads will continue to send the request, one to choose to stop running the script.Setting a reasonable number of threads can have a decisive impact on meeting the test targ
