We’ve been using beta and release candidate versions of FreeBSD 10 for some time, so that we were prepared to ship a major update based on FreeBSD 10, shortly after it’s announced. It has received lot’s of testing, with only a few issues (reported upstream). FreeBSD 10 brings numerous improvements, and we’re very pleased with its stability as well.
Some of the improvements that our customers will notice and enjoy are;
LDNS and Unbound as replacement for BIND (as resolver and DNS cache)
Hyper-V para-virtualization, bringing gigabit networking, VLANs, accelerated SCSI disk support, and much more.
Virtio (KVM) para-virtualization, for greatly improved network and disk performance
Support for VMware’s VMXNET3 driver
Support for Xen’s PVHVM mode, an hybrid virtualisation mode
Improved AES-NI support bringing higher encryption performance
Ability to grow mounted filesystems, allowing us to automatically resize the storage disk
