When copying a large amount of data from one folder to another folder on the same partition it is causing all other applications to become unresponsive, most noticably Firefox 11.0. Amount of data be copied (79GB) at a rate of between 18-30MBps, using the simple procedure of right clicking a folder, selecting copy and pasting it into another folder. During the copying process all other applications hang, or take a good 3-5 minutes to open up. Once open they become unresponsive - - all is rectified once the copy process is complete.

Similar behaviour is seen when creating a large (larger than physical RAM) virtual hard disk with VirtualBox, e.g. VBoxManage createhd --filename /tmp/temp.vdi --size 65536 --variant Fixed Becomes more noticeable as physical RAM increases.
On the original report: NonfreeKernelModules: nvidia so that one will be ignored anyway. Michael your report is in many ways completely different - it's not a cross device one and it's using different tools. Please can you open your own bug report and include the following important details - the memory size of the box - the kernel running - the modules loaded - the disk subsystem you have (what disks/controller etc) (note if you are running the non upstream virtualbox code you can probably repeat the test using dd to create a similar sized file with "dd bs=test.out bs=1G count=n" where n is however many GB so that you can test without any strange stuff loaded. I'll now close this existing bug as that should have been closed earlier
