The CPU utilization reaches more than 75% when I forward traffic using zt interface #17

I have installed zerotier in my openwrt Access Point. And created tunnel interface zt between two devices and run the iperf test. I could see the zerotier takes more than 75% cpu. I believe its not recommended. Any suggestion to reduce the cpu utilization is much appreciated.

Your devices CPU might not be strong enough. Another way to speed it up might be to compile ZT for speed instead of size (-S). I haven't tried that.

yes my cpu is not powerful. Can I have steps to compile zt for speed instead of size. Thanks in Advance

I do not know. I asked the question here: https://forum.lede-project.org/t/disable-size-optimization-0s-for-package/5150/1
