Hi @Seungjae-Baek,
It is hard to see the detail in the screenshot, it is very low resolution. Can you please clarify which cameras you are turning on / off?
Also, what streams are consumed from the camera server (by other processes) and what are the resolutions?
Also, keep in mind that your cpu may not run at a high frequency. Please check voxl-inspect-cpu for more details. If your cpu governor is in auto mode, it will reduce cpu core frequency, which will result in higher % usage of each core (at lower frequency).
If you sent your cpu to performance mode (voxl-set-cpu-mode perf), this will push the frequency of all cores to the maximum and will give you a better estimate of the cpu usage per process (out of the full core capacity). Please note that in performance mode, the cpu will consume more power (and heat up a bit more) to perform the same tasks (with lower latency).
