Comment 216 for bug 620074

I would agree that -rc6 has for some reason greatly improved system responsiveness under I/O load but there are most certainly still great issues in the block I/O world.

Just now I once again managed to completely wedge up my machine by doing nothing more than copying a few gigabytes of files between drives. Furthermore, Firefox still freezes for several seconds when I first start typing in the location bar as it looks in its history database. Lastly, Evolution still takes several minutes to start and become usable while it's I/O rate is less than 1 MB/s. All in all, things are pretty unusable.

Jens, are you around? I've been asking various distributions and vendors whether they could spare some qualified man-hours to get this problem finally worked out but it seems like you're our best hope. I know you'll be getting at least one case of beer when this is fixed ;)
