Hi Mike, I have tried with another raspberry and with another micro sd (class 10) and in another location and same behaviour: It takes hours to do a `freebsd-update fetch`. After tweaking vfs.hirunningspace it seems to help a little but the system still feels laggy. That's with a fresh install, no extra services or apps.
