Fixed: The Linux Desktop Responsiveness Problem?

[MaxToTheMax]

I haven't really noticed this problem since I stopped using swap. I also use the -ck patchset.

Would I benefit from this patch at all or should I not bother?

(I'm willing to test this if no one knows.)

If it ain't broken...tweak it.

I have 6GB RAM, so it's not a RAM issue.

Maybe there should be a swap priority setting that will tell the kernel to disfavor swapping out UI processes, since LRU (or whatever the current algorithm is) isn't working. All-or-nothing mlock is probably not sufficient for this. Maybe setting higher ionice levels for UI-related processes in the startup scripts would help, too.

I've got rid of this problem on my laptop after some realtime patches got merged and I set my scheduler to preemptible.
but it persists on my desktop ... I thought it was a bad working raid driver.

Yeah, I used to love the way that XP would swap out the web browser I was actively using when I was copying a 2GB file from one drive to another in the background.

Try Windows7 it's the same all the way.

Yup same deal on Win 7 Pro

Here, Windows 7 does not freeze when copying big files.

It does for some people including me

You also need to clarify what "freeze" means to you :P If you mean that the GUI gets skippy and lags a bit, yes I have that too. If you mean that the GUI is unusable for half a minute, then no, I only have that on Linux.

Do you have an SSD? Windows is notoriously know for locking up explorer (that's also the GUI) when devices are not responsive.

A lot of SSD's out there, especialy older SSD models, are know for being unresponsive when writing, because that usualy blocks reading.
