drama For some reason Nautilus is too slow and using too much RAM. This is not normal... I have only 3 GBs of RAM I just opened it and it consumes all it can.
nolan Is your installation fully up to date? if not, try to update, then check for any change in memory consumption.
drama Today it appeared an option to update, I did it and now it is fine with 60 MBs only, thank you all.
brent drama My nautilus has been wiggy lately but not like yours. Sometimes freezes and refusal to close. Seems the updates fixed me as well. Might've been an issue at devtracker; but I haven't been there in a week to confirm.
