Keep in mind that rpi are not the only cheap, capable arm hardware out there. I am using a number of odroid devices, including an N2 with a gentoo based kernel and a gentoo aarch64 userland. Its used for lxc containers for asterisk, dns, webdav, mail, calendaring and web running on the N2 backed by an Odroid HC2 moosefs cluster (though I am using an intel powered Odroid H2 for the master). Its all working rather well now the initial install/config stages are over. Part of the gain over the pi's is the use of eMMC storage over sdcards - almost 5 times faster in my tests. The 4G of ram has proven quite adequate so far - even the asterisk latency is better than my previous QEMU/KVM on intel setup. I have currently have rpi 1B, 3B and a zero and while the specs for the rpi4 are better ... its not the best out there. BillK
