Updating bsd vs debian
Dragon Fly is uniquely positioned to take advantage of the wide availability of affordable Solid Storage Devices (SSDs), by making use of swap space to cache filesystem data and meta-data.
This feature, commonly referred to as "swapcache", can give a significant boost to both server and workstation workloads, with a very minor hardware investment.
Over all course of all the deployments I've become very biased about my operating systems. Obviously different distributions of Linux have different scripts and standard locations so it's slightly difficult to compare apples to apples here but I'll do my best basing my experience off of Slackware, Debian, Redhat, Gentoo, Mandrake and Ubuntu.
Linux clearly has a solid lead with desktop applications, but for server deployments and maintainability, I believe firmly in Free BSD. I'd also like to note that Windows isn't included in this comparison simply because it follows a completely different paradigm.
Free BSD is more stable and faster than Linux, in my opinion.
