Kernel parameters stopped my lap to slowdown while copying files
I needed to move a 10GB file from a computer to another. Quick way: USB pendrive. I found out that the mouse moved weird while copying the files, and the rest of the things, well… stalled.
A quick search in the net revealed this:
https://bugs.launchpad.net/ubuntu/ source/nautilus/ bug/1208993
So, I applied the changes:
As root, edit /etc/sysctl.conf and add these lines:
vm.dirty_background_ratio = 5
vm.dirty_ratio = 10
Then update the configuration (to avoid rebooting):
sudo sysctl -p
Done ! Now I can copy files and continue working !
