piotr I'm not exactly sure, but dd is probably pegging your CPU.
see what happens to your performance when you are copying that 5GB file?
better a little I think than dd. Also, I have here rare configuration. My rootfs and home are on LVM, where this LVM is on dmcrypt. so raw storage <> dmcrypt <> lvm <> filesystem. It may reduce performance. I forgot to do tests without this patch so I cant say that this is faster or not.
Then I guess it's not better at all. :> I'll check myself if those patches make a difference. If the problem isn't fixed yet, then the best option is to report to lkml till somebody is trying to fix it.
I think I will provide more than just beer! This issue has been severely plaguing me in every ubuntu install on various types of hardware for years now. It's so bad that running virtual machines on ubuntu and linux is actually pointless. it does not work.
