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 from 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 -- J.
