TIL if you're running a virtualised FreeBSD server with a virtio NIC you really want hw.vtnet.csum_disable=1 in /boot/loader.conf

Before: 917 Kbits/sec
After: 47.1 Mbits/sec


Wheeee a 15MB scp copy that transferred at 128.2KB/s this morning now does so at 2.2Mb/s. So much better.

@wezm Wow, I checked out #FreeBSD on DigitalOcean but the package update was too slow, found out it was something to do with virtualization, didn't really follow up on it.
