I've just upgraded a Fedora 6 machine to Monday's rawhide and as a result
the performance under I/O load has hit rock-bottom. The machine was fine
under Fedora 6.
The machine is an Athlon XP 2100+ with a Gigabyte GA-7VAX motherboard
(nVidia nForce2 chipset). The hard drives are PATA, with the controller
listed as:
00:09.0 IDE interface: nVidia Corporation MCP2A IDE (rev a3)
There are 2 hard drives, and a DVD burner, all PATA.
Under heavy I/O load (for example, copying files from one hard drive to
another), Xorg gets extremely unresponsive, to the point where rapid
typing will sometimes result in the keyboard buffer filling up and
dropping keystrokes.
I observed exactly the same problem on another machine (which I no longer
have access to) when it was upgraded from Fedora 7 to Fedora 8 -
presumably something fairly major has changed in the kernel and has
wrecked the performance. Can anyone suggest any possible solutions?
