server performance testing tools

the problem, if the full log records, it is easy to find the problem through the log. For example, when the system goes down, the system log prints out an out-of-memory error when a method executes, and we can follow the lead and quickly locate the problem that caused the memory overflow. 2. Using performance monitoring tools, such as: Java Development B/s structure of the project, can be through the JDK j

[Original] Performance Testing Tool Introduction Commercial use Mercury LoadRunner LoadRunner is a load testing tool that predicts system behavior and performance. By simulating tens of millions of users to implement concurrent loads and real-time performance monitoring, Loa

The software performance is listed below:01. Is the system response time that the user understands fast enough?02. Is the resource usage of the Application Server reasonable?03. Is the resource usage of the database server reasonable?04. How many users can access the system at most? What is the maximum service throughput?05. Does the system support 24x7 business

TCP connection at hundreds of, the response time of the test is very long.packet Capture analysis, the original is three handshake SYN packet server is not timely response, resulting in SYN retransmission (3 seconds later, 9 seconds later). If the SYN is lost, it will be re-sent, but the first time is 3 seconds, the 2nd time is after 9 seconds, if the Syn_ack received after the re-send, it causes the TCP connection is very long,This results in exten

unique tool for network testing, automated networking, and data extraction, which not only records your work, but also replays your repetitive work. It can populate tables and automate the downloading and uploading of text, images, files, and Web pages, as well as easily import/export your data to a Web application through a CSV or XML file format or database or any other source.7.FitNesseFitNesse is a complete, stand-alone wiki site that includes a

the basis of HttpUnit, which provides commands to work with forms, examine the contents of the tables, and link between HTML pages. Users do not have to write long JUnit testcases or necessary XML files for testing, and the user simply writes a simple test script. Each line in the script file is a test node that contains a single command. All commands in the same file will be processed into a testcases. The syntax of each command is easy to learn, an

knowing how to test Apache performance. Now I have found a test tool. It is the test tool AB (APACHE benchmark) that comes with Apache. It is under the bin directory of Apache.Format:./AB [Options] [http: //] hostname [: Port]/pathParameters:-N requests number of requests to perform// The number of requests executed in the test session. By default, only one request is executed.-C concurrency number of multiple requests to make// The number of request

First, compare the throughput. When the number of concurrent users is 190 reqs/s, the maximum throughput is 200,500. When the number of concurrent users is, the throughput is reduced, a
