Docker Swarm Mode VS Docker Individual Performance

Hi All,

i’m doing in performance test between Swarm Mode and docker individual. i’m build server clustering for swam mode with 3 Virtual Machine and 1 VM docker convensional. with jmeter as below.

Physical server

3 Virtual Machine (vm-C71, vm-C72, vm-C73) as swarm mode.

I test both with JMeter with Thread group user 100, Ramp-Up Period 10, loop 1, Graph setting interval 1000. as i’m get result as below.


So from JMeter results as above i get conclusion that docker performance with swarm mode not better than docker individual.

Question

Is this correct? if not, what should i do with docker configuration or setting?

Nobody ever replied?
