why http performance so bad?
iris version: IRIS for UNIX (Ubuntu Server LTS for x86-64 Containers) 2019.4 (Build 383U) Fri Dec 6 2019 08:49:54 EST
os: Ubuntu 18.04 LTS
Disk: 256G SSD
Iris config: default.
soft/hard limit: 65535
I build follow simplest flow to do performance test.
1. create A EnsLib.HTTP.GenericService name it IncomingHTTPService listen on 9980
checked create connection per request
Keepalived = 0
Qsize = 1000
2. create A EnsLib.HTTP.GenericOperation name it OutgoingHTTPOperator to connect localhost:8080(it's a nginx server serve a static html page)
3. connect line from IncomingHTTPService to OutgoingHTTPOperator.
I use jmeter to execute load test, the config params as follow:
Number of threads: 1
Loop Count: Infinite
But I got a not good performance report. About half request failed. And throughput is too small.
Do I need tune some system param in order to improve http performance?
