Currently, well-known concurrent performance testing tools include rational robot, qaload, LoadRunner, and Microsoft was. Among them, qaload, LoadRunner, and rational robot are all good commercial testing tools (expensive). Microsoft's was is a free testing tool that is easy to use, however, because the recorded test script cannot be displayed or edited, its controllability and graphical test results are weak, which causes some limitations.
Opensta is a free performance testing tool dedicated t
worker thread, has the data, the worker thread carries on the message parsing and processing, sends the data to send the queue, then notifies the main thread, has the data, you go to send the.This model can deal with the complexity of logic, long processing time, the need to send and receive less data is more appropriate situation. But if you need to deal with a file server like this, IO data a lot, but the logic is very simple server, it is not appropriate, the main thread will become a bottle
