Thank you for the answers. I enjoy opnsense, it’s easier to use then openwrt for me personally.
I was thinking to do some testing of the new device before I replace the old one. But I wanted to hear if anyone has experiences.
I looked at CPU benchmark net, and saw that N100 is about 8 times faster then the AMD SOC. I’m not sure if this is linear with performance increase. Currently max download is about 600-700 while upload is 300-400.
