Hi, My system tends to slow down a lot when I copy files to and from a pen drive or even from one hard disk to another. Even my mouse cursor slows down. The system becomes almost unusable. I more than enough RAM and I am using a tiling window manager. So I am not even using a lot of RAM. Why is this happening? I can't work on my system if I run any large file copy/move operation. Please help. Thanks.
If you have 1GiB or more of RAM, one cause in recent kernels can be transparent hugepages. Disable it from boot with transparent_hugepage=never on kernel cmd param. Maybe this is fixed in newer 3.0, I do not know, I still have disable, some day I will test again if was improved. -- Gerardo Exequiel Pozzi \cos^2\alpha + \sin^2\alpha = 1
