A typical server performance testing tool described is well known that the entire network system and the server is the core of computing platforms, many important data are stored on the server, many network services are running on the server, so server performance is good or bad for the whole application system performance. 0 D $ `'^ & m0 f
now available in different brands, different types of servers there are many users in the purchase, how to choose from numerous models out the need for application servers in their own products, only from the configuration is not enough to determine the best practical test to filter through. The variety of evaluation software, there are many, you should choose which software testing? Here are just some of the more typical test tools:
(a) of the server machine system performance testing tools
the performance of a server system can follow the processor, memory, storage, network parts to divide, but for different application, may have some part of the performance requirements of higher
Iometer (
www.iometer.org): storage subsystem to read and write performance tests
Iometer is a Windows system to read and write to the storage subsystem performance testing software. Can display the maximum IO capacity disk system, disk system, maximum throughput, CPU utilization, or error messages. Users can set different parameters of the test, there are access type (such as sequential, random), read and write block size (such as 64K, 256K), queue depth, to simulate the actual application of the literacy environment for testing.
C0 lIometer

Iozone (
www.iozone.org): linux under the I / O performance tests
There are a lot of server systems are based on the linux operating system, to test the linux platform I / O performance can iozone.
Q iozone is a file system benchmark tool, you can test different operating systems file system read and write performance. To test the Read,
nike air force, write, re-read, re-write, read backwards, read strided, fread, fwrite, random read, pread, mmap, aio_read, aio_write so different mode hard disk performance. All of these aspects of the test, generate excel file, the other,
air force one shoes, iozone also comes with a script using gnuplot drawing. The software used in large-scale
cluster system to test the performance of NFS, more persuasive
Netperf (www . netperf.org): network performance testing
Netperf can test the server network performance, mainly for TCP-based or UDP transmission. Netperf Depending on the application, can be different modes of network performance testing, that is, bulk data transfer (bulk data transfer) mode and a request / response (request / reponse) mode. Netperf test results reflect a system is able to more quickly send data to another system and another system is able to receive data more than the speed of the block.
tools to client / server manner. server side is netserver, used to listen for connections from the client side, client side is netperf, used to launch network test server. Between the client and the server, first create a control connection to pass the relevant test configuration information and test results; in the control connection is established, and after passing the test configuration, client and the server will then create a test between the connection with to pass back and forth a special traffic patterns to test network performance .
for server systems, network performance is particularly important, some of the server in order to save costs, the use of a desktop-class network chip, performance event, a test with a glance of this software.
described above which are several test tools can be downloaded for free non-commercial software, but recognition of the extent of their test results and are recognized by most users. You can choose according to their different software applications for testing.
b) application testing tool for web applications
With the increase,
air force 1 shoes, the server application solutions in the Web as the core applications are more and more, many companies have a variety of applications to web application framework based. General web application testing and past the focus of the test are not identical in basic functions have been tested, it has to be an important system performance testing. Performance of the system is a great concept, covering a very wide terms of a software system including the implementation of efficiency, resource utilization, stability ,
nike air force one, security, compatibility, reliability, etc., the following key aspects from the load pressure to introduce server performance tests. System load and the pressure to use load testing tools, the virtual number of users to test the performance of the system to see if the design requirements to meet the expectations. The goal of load testing is to test when the load gradually increases, the system component, the corresponding output items, such as throughput, response time, CPU load, memory usage, etc. How to determine system performance, such as stability and response and so on.
load testing is generally done using a tool, a LoadRunner,
air force 1, Webload, QALoad, etc. The main content is to write test scripts, the script generally used functions, including user and then run the report
obtained using the stress testing tools stress tests on the web server. Testing can help find some large issues, such as crashes, collapsing loss, memory leaks, memory leak problem because some programs, when you run one or two may not be a problem, but if you run thousands of times, more and more memory leaks, it will cause the system to landslides.
Loadrunner: predict system behavior and performance load testing tools
present, the industry can do in a number of performance and stress testing tool, Mercury (Mercury) Interactive's LoadRunner is one of the best,
cheap air force ones, but also has become the industry standard, the latest version of 8.1.
ELoadRunner is a forecast system behavior and performance load testing tools, by simulating tens of millions of users with implementation of concurrent real-time performance monitoring, load and ways to identify and find the problem, LoadRunner to test the entire corporate structure, LoadRunner applicable to all kinds of architecture can support wide range of protocols and technologies (such as Web, Ftp, Database, etc.), to predict system behavior and optimize system performance. It is the operation by simulating actual user behavior and implementation of real-time performance monitoring, to help you find and identify problems more quickly. Loadrunner is a strong and effective stress testing tool that can record the script generation, automatic associations. Test scenarios for the target to achieve a multi-party monitoring. And the test results using charts, free to split the test window interface combined
Loadrunner Loadrunner the test results through the comparison chart, you can find out the reasons for bottlenecks in the system, in general, can follow the server hardware, network, application, operation systems, middleware sequence analysis.
Loadrunner Loadrunner analysis window is a billing software interface, test items and virtual users based on the number of different fees to different cost. But you can download the free 10-day test version.
Webload: WEB performance stress testing
Bwebload is RadView Launches a performance test and analysis tool that allows web application developers to automatically perform stress tests; webload operation by simulating real users, generating pressure load to test web performance.
