I just upgraded to RELENG_8. Now it's behaving more like FreeBSD should. I can do sequential reads/writes and still use kbd/mouse/X11/buildworld and so on. Yes, the cpu is still completely underwater, and allowing for that, it seems interactivity is nearly back to normal. ZFS is taking up a power of 10 less cpu than before. Geli is at it's rightful place on top of the cpu/time list. And where copying GiB sized files would sink the system requiring the reset button, it just keeps on copying. If anyone's having issues with similar setup/loads, all I can say is upgrade asap. [OT] If you do installkernel installworld mergemaster reboot all in one uptime session, 'ln' will core in some places. Just replace it in the makefiles with cp -p and rerun whatever stage cored. once you reboot into 8, all is well.
