The RPi4B is the fastest at buildworld buildkernel of the small boards that I have (or had) access to, and not by a small amount. The same goes for building ports via poudriere. I've set that up on the RPi4B to allow 2 builders, each allowing 2 processes, so 1 to 4 processes generally active. Still, having access to the likes of an OverDrive 1000 and a MACCHIATObin Double Shot for use as builder machines is nice. (I get them going in parallel.) I also build for armv7 on them. > I keep thinking about the double shot for my next router, do you > know how well it does PPPoE under FreeBSD (or anything else for that > matter) ? The built-in Ethernet is not supported. I just use a USB3 Ethernet device. I'm using a Realtek USB3 10/100/1000 LAN device via using https://reviews.freebsd.org/D25809 in order to use much of the Gbit bandwidth. But I'm not using the MACCHIATObin as a router or for PPPoE or anything like that, just for occasional transfers of files between local machines and some local ssh use into it. === Mark Millard marklmi at yahoo.com ( dsl-only.net went away in early 2018-Mar)
