Apache ab

Apache ab

Note:

The parameterized value of [1]-n cannot be greater than the value of the-c parameter, otherwise it cannot be used

[2] apahe ab can perform stress tests for both get requests and post requests, but url must be enclosed in double quotation marks in post requests.

[3] the number of concurrent users and TPS measured by apache ab are larger than those measured by loadrunner, because apache ab does not accept the return value of the server, and loadrunner needs a complete return value of the receiving server. Therefore, under the same response time, the number of concurrent users measured by apache ab is larger than that measured by Loadruner.

Secondly, the concurrency number measured by apche ab is also related to the number of CPU particles installed in the apache ab machine. The larger the number of CPU particles, the greater the number of concurrency supported by the test results.

[4] apache ab test results mainly focus on indicators: number of concurrent users, response time, Requests per seconds (equivalent to TPS of loadrunner), transaction success rate.
