Test host's network connectivity performance with DOS command

Http://www.aliyun.com/zixun/aggregation/14356.html "> Performance test is to test the performance of the system by simulating various normal, peak and abnormal load conditions through automated test tools. Both load and stress tests are performance tests that can be combined. Through the load test, the performance of the system is determined under various workloads, and the target is to test the change of the system's performance index when the load is increasing gradually. Stress testing is the maximum service-level test that a system can provide by identifying a system bottleneck or a performance point that cannot be received.

After the system trial runs, it is necessary to know exactly what is happening on the network, what applications are running, how many PCs are accessing the LAN or WAN, and which applications are causing system bottlenecks or resource competition. Then network application performance monitoring and network resource management is very important to the normal and stable operation of the system. Using the Network application performance monitoring tools, can achieve a multiplier effect, in this respect we can provide the tool is receptacle Vantage.

In layman's terms, it is primarily used to analyze the performance of key applications, and the root cause of the problem is the client, server, application, or network. In most cases, users are more concerned about which applications are consuming a lot of bandwidth and which users are generating the maximum network traffic, and this tool can also meet the requirements.

How to test the host's network connectivity performance, we all know to use Ping, but the website service is 24 hours, you can not every once in a while to ping it, tired not tired ah! First of all, DOS Ping:

Ping, this command is the most commonly used

PING-T-N 10-l 1000 wangblog.org,-t is command CTRL + C to stop Ping,dos The default is Ping4 secondary connection, this is different from FreeBSD;-N 10 is the command ping10 secondary connection;-L 1000 is the command to request a 1000-byte packet at a time, no more than 65500 bytes.

Ping-?, command Help
