I have one CentOS physical machine(CPU: 56, MEM: 512G) and JVM(-Xmx=4g, -Xms=4g, -Xss=256M)
I use constantUsersPerSec method
param set 15000
, report is: pic1
param set 20000
, report is: pic2
param set 25000
, report is: pic3
First, the tested backend service have no performance, because I have three CentOS (every machine param set 10000 == total 30000) to load it, it’s OK.
pic3 why?
the single gatling only can request 20000 constantUsersPerSec?
thanks!
