We’ve been using beta and release candidate versions of [FreeBSD](http://www.freebsd.org) 10 for some time, so that we were prepared to ship a major update based on FreeBSD 10, shortly after it’s [announced](https://www.freebsd.org/releases/10.0R/announce.html). It has received lot’s of testing, with only a few issues (reported upstream). FreeBSD 10 brings [numerous improvements](https://wiki.freebsd.org/WhatsNew/FreeBSD10), 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](http://www.unbound.net) as replacement for BIND (as resolver and DNS cache)
- [Hyper-V](http://en.wikipedia.org/wiki/Hyper-V) para-virtualization, bringing gigabit networking, VLANs, accelerated SCSI disk support, and much more.
- [Virtio](http://wiki.libvirt.org/page/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
- Using the innovative [clang](http://clang.llvm.org) as compiler

In addition to this, we’ve overhauled large portions of our systems (this is a major release, after all), including (but not limited to);

- Line graphs showing performance metrics such as disk IOPS and latency
- Show message modifications when browsing queued or quarantined messages
- Overall throughput increased by careful profiling
- Many cute optimisations in our scripting language, such as 
    - Pre-compiled regular expressions
    - Optimised augmented assignments

It’ll be available within short, when it has passed its testing phase.
