And it seems to get more heated later in the discussion.

And there seems to be no clear winner. At least, not one I feel qualified to call.
I think I.m going to go ahead and play around with it a little.

Actually recording video REALLY seems to take quite a bit of horsepower.

Under Cheese with the 1.6, I was getting about a 20 sec. freeze frame at 128 x 96. With the 2.4, I was getting iffy 320 x 240. With this patch alternative, it's getting pretty acceptable (noticeably better) 320 x 240. > > The guy who worked this out works for RedHat and I'm guessing is using RH Enterprise Desktop.

It is being highly debated on LKML, and all the kernel devels that I know personally are going with Mike Galbraith's kernel patch versus the hack from Lennart Poettering -- including Linus. Here's the LKML thread with the original info about the patch: http://lkml.org/lkml/2010/10/19/123 where I noticed a while back. I have patched it against 2.6.36 and am now running it on 2.6.37-rc2. If you go look at Hot Messages on LKML you'll get an eye full. This is the type of thing that comes around ever so often, and why I am always testing new git kernels. ;) Over the years some pretty interesting changes have ocurred, and I suspect when 'the dust settles' on this issue, we are going to see some serious performance gains integrated into the mainline kernel; not some spurious hack such as CK patches have been over the years. ;) Just my 2c Bruce -- May the Lamb that was slain receive the reward of His suffering!
