This article mainly introduces how to use the ab stress testing tool in apache. It is very detailed and has a certain reference value. Friends who are interested must read it!

I. script description

The script supports most of the commonly used parameters of ab, if you need more parameters, you can modify the script to add what you want.

The script supports:

1), batch testing. Note that it is not a simple batch test, you can determine the number of test wheels and the interval. 2), ladder concurrency growth custom testing, such as concurrency from 100 to 1000, 5 tests per round, etc. 3) postfile mode that supports ab, you just need to include your data file in the parameter-P |-- postfile. 4) the analysis of the index of pressure test shows that this shell can analyze the instructions commonly used in ab in real time.
