Slow xorg after upgrade

Thanks to all who replied; it's fixed.
Adam, you hit the nail on the head. It turns out that xorg was looking
for intel_drv.so, which is correct, but that driver had "somehow"
vanished from /usr/local/lib/xorg/modules/drivers. Failing to find the
Intel driver, xorg fell back to the modesetting driver.
I didn't expect a previously-working driver to be deleted like that, so
it wasn't the first thing I looked for. Anyway, the fix turned out to be
as simple as
# pkg install xf86-video-intel
