Disable Mac OS X Paging / Swap
I wondered why a Mac with a full 64Gb RAM was swapping even for simple surfing. I was seeing inexplicable beach-ball appearances. So did this:
Which switches the swap off and deletes the swap files.
My own process monitor confirms the machine runs slightly faster now, and have not seen the beach-ball since.
There is probably a down-side, but have yet to hit it.
sudo launchctl unload -w /System/Library/LaunchDaemons/com.apple.dynamic_pager.plist
sudo rm /private/var/vm/swapfile*
Which switches the swap off and deletes the swap files.

Mac Pro Wifi and Bluetooth reception problems?
On your Mac Pro do you have issues with your Wifi reception quality, and Bluetooth connectivity?
Does the Wifi seem very weak, even though the router is just across the room?
Does the Bluetooth need you to be right up close?
Bizarrely it might be that the Airport and Bluetooth modules inside the Mac Pro were connected to the wrong aerial leads at manufacture.
Well, take a look at this page, especially the note following Step Five.
