Thanks for your reply, There is one more problem, I’m running apache httpd server inside docker container on linux (centos 7) machine. I’ve placed container behind the bridge. Now I want to measure the overhead incurred by docker bridge. How can I do that ? I used perf tool for cpu profiling, but I can’t infer from that the cpu used when the packet is moved through the bridge (the overhead added because of the bridge). From that I can get the total cpu usage of all the processes of a particular container. I got that around 2/3rd of cpu used in kernel mode and 1/3rd cpu used in user mode by httpd processes. How can tell from it that what percentage of cpu was used executing the bridge functions ?
