My "mixserver" have certainly far different mix of your "mixserver", as i don't use python heavily for example, while use squid, clamav (both fits well in superpages), and don't run large memory postgres process. What is "desktop". A computer sitting on the desk? May run a lot of different programs. Your "desktop" as i can see use KDE bloatware and postgres. As for me, such namings are completely imprecise and such statistics say NOTHING. What REAL knowledge i acquired from your work is that postgres are very well fit for superpage mapping, if large DB buffer is used. Actually - Whenever there are long running processes in the system that allocate and use large memory chunks then superpage promotion will work. My idea - lets do a survey based on PROCESS NAME. this will give a really meaningful information.
