I've upgraded RB133 from v3.10 to v3.30 with firmware 2.18. I've checked all the settings, and they are all intact. The CPU usage is about the same average 8% just setting and during bandwidth test to speedtest.net it goes up to 30%. But noticed during bandwidth test, it's slowed by 26%.
Is RB133 CPU not fast enough to handle v3.30?
I'm considering RB333 upgrade from 3.30 to 4.2, anyone noticed any performance decrease?
