Run a multi-threaded program in the Docker, container starts not to do any restrictions on the CPU and memory, but found that only use the program on the host CPU core0 core, unable to break through 100% CPU utilization, which can lead to can't play a multithreaded performance, don't know is what reason, where is limited, a great god, please advice!
In addition, in the same container, run the iozone test tools, and multithreading test, no the CPU limits,

CodePudding user response:

Restricted multi-threaded programs are based on the upper of DPDK applications, a great god guide genuflect is begged!

CodePudding user response:

Check the have set the reserve resources

CodePudding user response:

refer to the second floor cqyy725 response:

check is there any set up reserve resources

core0 did the isolation of the CPU can appear the above phenomenon, isolation, there is no wrong core0 do multithreaded performance limits, will depend on the docker deamon process core0 assign any special? Need to further understand,,,
