Description: Http_load is run in parallel multiplexing to test the throughput and load of the Web server. However, unlike most stress testing tools, it can run in a single process and generally does not kill the client. You can also test site

None of the following are tested, just the retention of the method First, Http_load The program is very small, after decompression is less than 100K The http_load runs in parallel multiplexing to test the throughput and load of the Web server. But

The two examples of the standard of Http_load are: 1.         Http_load-parallel 5-fetches urls.txt2. Http_load-rate 2-seconds Urls.txt example is only a reference, the parameters can be freely combined, the choice between the parameters is not
