The API performance test script automatically executes wrk commands, collects data, analyzes it, and calls gnuplot to plot it

Usage (to test API performance) :
1. Start the openim-api(port 10002)
2. 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
2. Execute the command:./wrktest.sh diff apiserver.dat http.dat

&gt;  Note: Make sure you have wrk and gnuplot installed on your system
