Hi to all; I have a system where I will be running 5 VBox VMs (3 W2K3, 1 XP & 1 Linux) for a lab simulation (work obligations). I have already ran the 5 VMs with a regular load on each and everything went fine. I think VBox is truly a great VM Manager, and it runs better (smoother and faster) in FBSD than in any other OS I tried it (Ubuntu, Winblows and OpenSolaris (!) ). Along the years, I've been running FBSD, picking up info from any "Tuning FreeBSD" guide I could find, starting with the handbook of course, going through articles and mailing list archives, trying to find a balance that would fit my desktop, among the several roles FreeBSD is used for. I would like to expose the hardware/settings I have now to the list, to see if what I've done is appropriate, over or under rated (or simply stupid), to squeeze every drop of performance FreeBSD can give with what I have. It is pretty fast as it is but it never hurts attempting to make it even better. Please bear 2 things in mind: 1) I am trying to learn here; 2) This is a Desktop machine (not a server!), sitting on my home LAN, behind a properly configured (again, to the best of my modest ability) firewall. It is used for everyday tasks, plus developing and music production. I am posting what I believe to be most relevant. Thank you all before hand for any advice.
