F18 XFCE Memory usage and Optimizations

view story

http://forums.fedoraforum.org – Hi there, I was wondering Why F18 with XFCE4 using too much memory ? (in my case after start it's cca 850MB of RAM) and after drop cache drops to cca 450MB ? I install F18 from Live DVD and there was too much applications that I didn't use, so I removed some apps from XFCE group and I think it's still enough apps. I also masked some unneeded services and editted some confs for speeding up system, but RAM usage is almost the same. Why system can't automatic drop cache? Is there some tips for cut XFCE4 to small apps and memory usage ? I used Win7 before F18 and it consumed only 650MB of (HowTos)
