Same here on a Dell Latitude E5510, which I updated to 14.04 these days. I have compiz enabled.
For me, CPU consumption begins right after executing nautilus, while nautilus consumes approximately 25% to 40% of the cpu according to top. It seems as if as if all 4 threads of my dualcore cpu are in use by nautilus. Once consuming cpu, it does not stop anymore until I close nautilus. Definately, it is unusable that way on a laptop on battery. Capacity drops from 5-6 hours to 1-2 hours just because of nautilus. Please fix this annoying bug which seemed to be active for years now. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to nautilus in Ubuntu. https://bugs.launchpad.net/bugs/1069843 Title: Nautilus consuming memory and cpu Status in “nautilus” package in Ubuntu: Confirmed Bug description: I noticed that Nautilus seemed sluggish after updating to 12.10 yesterday. Clicks in the window may take a moment to register and the right click menu takes a few seconds to draw. This happens in nautilus windows and on the desktop, but I have not seen this behaviour in any other windows. I checked nautilus in the system-monitor and found that it was eating an excesive amount of memory (14.1/16 gb) and 72% of one cpu-core constantly. The memory starts out low at ~300mb ram and creeps up from there.
