The performance test simulates various normal, peak, and abnormal load conditions through automated test tools to test the system's performance indicators. And the performance of the app is getting more and more attention, let's i

JNI/NDK Development Guide (9) -- JNI call Performance Test and optimization, jnindk Reprinted please indicate the source: http://blog.csdn.net/xyang81/article/details/44279725 In the previous chapters, we learned to declare an native method in Java, then generate a prototype Declaration of the Local interface function, and then use C/C ++ to implement these functions, and generate a dynamic shared library

Original address: HTTP://WWW.16ASPX.COM/ARTICLE/62In the context of Web performance testing, the addition of loops (Loops) and Conditions (Conditions) allows developers to write more complex, smarter tests for their applications, with 64-bit agents and controllers added to the load test. Enable testers to use the available hardware resources more efficiently to generate load. In addition, the licensing of l

Labels: How to Use OS file data in HTTP Linux Performance testing uses automated testing tools to simulate a variety of normal, peak, and abnormal load conditions to test the system's performance indicators. Both load testing and stress testing are performance tests, which can be combined. Through the load

This article is forwarded from Jason's Blog, the original link Http://www.jasongj.com/2015/12/31/KafkaColumn5_kafka_benchmarkSummaryThis paper mainly introduces how to use Kafka's own performance test script and Kafka Manager to test Kafka performance, and how to use Kafka Manager to monitor Kafka's working status, and

Performance testing objective: to locate the current server bottleneck through high concurrency stress testing. Performance test scope: (analyze logs during peak business hours) 1. socket-related (Instructor-side network monitoring, whiteboards, Allocation Analysis cards, exercise cards, student-side network monitoring, and student questions) 2. HTTP interface (a

some time ago, I saw MacLean Liu share a good article on Exadata I/O performance calibration: Calibrate Test Exadata IO, this article basically covers the exadata I/O performance calibration method. Just recently someone has asked me this question, so I will try to make some additions to the fish, there is duplication of places please ignore it. If I/O

LoadRunner Result Analyzer (hereinafter referred to as analysis or analysis module) is a stand-alone module, it can transform test results and monitoring data into database data, for the benefit of analytical processing. Testers can select the icons of interest in the analyzer, analyze the test results and monitoring data by merging graphs, cross graphs and automatic correlation, to determine the

disconnect (connid) is used to actively disconnect the client.3. added the cserversocketlistener subclass of iserversocketlistener to provide the default (null) Notification processing method. > Client: -----------------1. The onpreparesocket (connid, socket) notification method added to iclientsocketlistener is used to set socket options before using socket.2. Support for asynchronous CONNECT: Add a parameter (bool basyncconnect) to the START () method of isocketserver to set whether asynchro

At first glance, you may feel that this is a functional requirement and how it is related to performance. But this is indeed a performance problem, if the transfer of the staircase built too narrow, will lead to a large number of passengers can not evacuate the moon caused by accidents, and if the construction of too wide will bring unnecessary waste, the appropriate evacuation capacity is the

In the previous article we introduced the differences between Redis and Couchbase and show their respective strengths (please poke the blue bold font: Couchbase vs Redis, which one is better. ）。 This article will provide developers with the most real and powerful data support, so that technology selection more objective, so that the cluster expansion is no longer blind, in the predictable business scale, so that each machine to do their material. ¡ø Testers: 杨挺, Song Jiayang ▲

Many companies are upgrading their wireless networks to 802.11n to achieve higher throughput, wider coverage, and higher reliability, while ensuring Wireless LAN (WLAN) to ensure sufficient network capacity and coverage. Next, we will discuss how to use iPerf to measure network performance. This is a simple and easy-to-use tool for measuring the throughput, loss, and latency of TCP/UDP. Preparations before application IPerf is a tool dedicated to sim

Flexibility, port density, and scalability are the biggest features of the Gigabit access switch. Therefore, we must carefully consider these parameters when purchasing them to suit our needs. The purpose of this evaluation is to make an objective comparison of each manufacturer's Gigabit Ethernet products. The main purpose of this comparison IS to provide the IS Administrator and other IT professionals with information that helps them make device procurement decisions. Therefore, our tests are
