Thanks for all these great tips. I'm building a new workstation and I'll 
probably buy an ssd and use it as root. I'm thinking about maximizing 
the amount of ram and then use tmpfs for /tmp. This will (hopefully) 
still leave me with enough memory to avoid swapping all together so I 
can put the swap partition on a spinning platter drive.
The only thing that still leads me to doubt is the fact that I won't be 
able to use dedup on the ssd and compared to using a couple of 10,000rpm 
disks in raid 0 the random write performance is not that impressive.
