Hi, not sure what you mean by "hot cache" - I always use devel/ccache-static as have tended to build from source throughout my time of using freebsd. It provides tremendous speedups and generally i'll disable it only if a problem arises and am debugging it, or crossing a version boundary like =66rom stable to current. What I'm saying is I don't know when ccache was last used for building anything. 1. rpi4 here is clocked to 2.0GHz 2. ccache is in use and /var/cache/ccache has *not* been previously cleared (i'll clear it for next test) 3. make cleanworld cleandir clean has been run on /usr/src 4. sources are at 246839 5. this rpi4 has the following properties for its disk: [i] root-on-zfs [ii] boot-to-usb3 [iii] 4k sectorsize forced [iv] encrypted swapspace [v] entire filesystem encryption /etc/src.conf is https://cloud.zyxst.net/~john/FreeBSD/rpi4-main/src.conf make -j10 cleanworld started on Sat May 22 15:41:58 BST 2021 make -j10 cleanworld completed on Sat May 22 15:43:23 BST 2021 make -j10 cleandir started on Sat May 22 15:43:23 BST 2021 make -j10 cleandir completed on Sat May 22 15:43:50 BST 2021 make -j10 clean started on Sat May 22 15:43:50 BST 2021 make -j10 clean completed on Sat May 22 15:44:11 BST 2021 make -j6 buildworld started on Sat May 22 15:44:11 BST 2021 make -j6 buildworld completed on Sat May 22 16:20:48 BST 2021 make -j6 buildkernel started on Sat May 22 16:20:48 BST 2021 make -j6 buildkernel completed on Sat May 22 16:49:18 BST 2021 --=20 J. --Fkz7UvI/hIn2nsgu Content-Type: application/pgp-signature; name="signature.asc" -----BEGIN PGP SIGNATURE----- iQIzBAABCAAdFiEE8n3tWhxW11Ccvv9/s8o7QhFzNAUFAmCpKr0ACgkQs8o7QhFz NAUzVw//VGFg8kQkZqbWJo1+uTv3WFtJIVLaElDSxJma/nDR6Rhheo1BggkG8Vsf IZHVAosNhI0i3FMFN+WqCX2kEfB1HBU0Tlz2A5fXopWdq6d08HBKuSeD4qFo46ZL ItSezZPNQzgh5QTxKeJb3KTS6RLa7dGvZxOnB5/GJxLjLBqXehEL7FDrT7YfJe2t 3Xrm3m7z6Ay6SgxTk3GVUJEMM8nqT5ubSlCxTKQ5jsTdMdlnH2T62rZPAh5FAlB6 zPWkP9+yFGrfn/fSQV+6t/mV0hVzL/bhdGGV5YGT8q+tMhlXUL5IrUaKA9Zx+1Zx U3KxS6NmYHlHUziNJDl6kYQnZ9JVYiwDoytz2aJzzL39bQn58bZw9Oc6F/HxxU41 kja6f6mWmslu49OA/L14PUy5pd5jgzJZvmAUZtxsb5mrKMp7EUT//qUdCCn6lQ4Y KVZ/zT2FXKiquwub8kyokiZz64vdjsa182jOrl6mpqYVPGeMVk39vs9bloxiEjoB OrPiqO7tA/7IpWjL5e5a+tUi5nhk6FgiS1AUEKFw0fTpkLaQb77NeGx3o6t5R5IL gOZDjTnKPVhdwEbo5JN4sKGg6S7PTNOU+//m32wyzIYgPbf9yAUdtDaP6Gqz/Dr7 hdHdDoIJ+pld3GklpZYB885jB8YZNpAnwfTdJ8XoKzo6OC+gK64= =Fhs2 -----END PGP SIGNATURE----- --Fkz7UvI/hIn2nsgu--
