Pylot is an open-source Web Performance Testing Tool for http://www.pylot.org/
Reference: http://www.pylot.org/gettingstarted.htmlvery easy to use
You can perform the following four steps:
Step 1: Create a testcase (the configuration is flexible in Reference Documents)
Step 2: Test Solution
Agents: number of concurrent users
Rampup: the time used to start all agents, which are evenly distributed within the specified time range.
Interval: the intermittent time for each agent to send requests (unless the response time exceeds the gap time, this will wait for the response to send the next request)
Duration: the time when testcase runs.
Step 3: Start mode:
Run Modes
Blocking Mode
Gui Mode
Step 4: view results
Such as: http://www.pylot.org/samples/results/results.html
Response time (SECs): Response Time
Throughput (req/sec): throughput, that is, QPS
STDev: Standard Deviation
99th %: the value at the 99/100 position after sorting. Other values are similar
