The API performance test script automatically executes wrk commands, collects data, analyzes it, and calls gnuplot to plot it
|
||
|
|
|
||
|
|
Usage (to test API performance) :
|
||
|
|
|
||
|
|
Start the openim-api(port 10002)
|
||
|
|
|
||
|
|
Execute the test script: ./wrktest.sh
|
||
|
|
|
||
|
|
The script will generate the data file.dat, each column meaning: concurrency QPS average response time success rate
|
||
|
|
|
||
|
|
Usage (Compare the results of 2 tests)
|
||
|
|
|
||
|
|
1. The performance test:. / wrktest. Sh openim apiserver - http://127.0.0.1:10002/healthz
|
||
|
|
|
||
|
|
Execute the command:./wrktest.sh diff apiserver.dat http.dat
|
||
|
|
|
||
|
|
> Note: Make sure you have wrk and gnuplot installed on your system
