Normal pressure measurement: single machine to the target machine can be pressure tested, the pressure generated is relatively small, restricted factors including CPU, network, and so the IO
distributed pressure test: using a plurality of machine-generated pressure to the target machine, tens of thousands of simulated users concurrent access (FIG simple example of what is distributed by the following pressure test)
If ordinary pressure measurement, if the stand-alone configuration is not high, it may initiate up to 10,000 concurrent, target of less than 40,000 concurrent, so will the introduction of distributed pressure measurement technology.
First, what is distributed test
Distributed testing is through the local area network and the Internet, to be distributed in different locations, the purpose of testing the computer independently connect specific functions to achieve test resource sharing, decentralized operations, centralized management, collaborative work, load balancing, testing, process monitoring, etc. computer network testing.
Second, the implementation of the principle of
1, wherein the selected one as the scheduling unit (Master), other machines as the execution unit (Slave)
2, execution, scheduling the opportunity to send the script to execute on each machine (Slave), the actuator (Slave) after script to get started, do not start GUI
3. After execution, execution machine (Slave) will result back to the scheduler, scheduling information phone the opportunity to perform all the machine (Slave), and consolidating
