Same issue here when moving ~250.000 or more (mostly small) files from USB (ext3) to USB (NTFS). Speed gradually slows down to just a few kB/sec, memory use gradually goes up to multiple gigabytes. Nautilus uses 99% CPU (180% when doing two copy/move tasks) and does not release memory when the move is finished.
I've attached a valgrind log of moving almost 6 million files (110GB), during which after about 67000 files the system became totally non- responsive due to swap hell, so I had to REISUB it. Memory use for the valgrind/nautilus project had grown to about 3GB at that point. ** Attachment added: "valgrind.log" https://bugs.launchpad.net/ubuntu/+source/nautilus/+bug/491736/+attachment/2950984/+files/valgrind.log ** Changed in: nautilus (Ubuntu) Status: Invalid => New -- 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/491736 Title: nautilus takes a huge amount of memory when copy-pasting files Status in “nautilus” package in Ubuntu: New Bug description: Binary package hint: nautilus My system has 2GB of RAM and 4GB of swap. Nautilus is taking almost all of them. Top says 1781M virt and 1.2G res. This happens as I´m doing a backup of my external USB drive into another USB drive. Around 1.000.000 files, with music, videos, text, and thousands and thousands of pictures. Copying from Ext3 to Ext4 partition, with a simple copy and paste. Copy speed decreased with time, starting around 16-17MB/sec now around 11MB/sec. Serious bug. Copy & paste shouldn´t destroy a machine no matter how big the amount of files/total size. =( I posted this originally as a comment, but this is a different behaviour to the one described on the bug report that I posted on.
