Solved ?: IDE Performance lack !

Solved ?: IDE Performance lack !

[Guido Stepken]

Hi !

My performance problemes have disappeared. I recompiled the kernel with:

(Direct) PCI access mode
APIC and IOApic   == OFF
SCSI competely == OFF
NE1000/2000 Modules compiled in as Module (directly compiled in did not work)
Changed BIOS PCI Mode to AUTO (perhaps useless)

Now my performance is normal, with and without hdparm optimisations (tnx to 
posters)

IMHO, there are still problems with interrupts (is thre still one 
interrupt/IP paket ??)

regards, Guido Stepken

Hmm, strange. My PCI-Mode is (Any), I have APIC enabled
CONFIG_X86_GOOD_APIC=y
CONFIG_X86_UP_IOAPIC=y
CONFIG_X86_IO_APIC=y
CONFIG_X86_LOCAL_APIC=y

And I use SCSI. 
I do not have any Problems. Do you have these Problems under heavy
load, or when your machine is idle?

Hmm. hdparm -d1 should AFAIK always speedup your IDE-HD
I have about 6MB/s without and about 26 MB/s using DMA

Dont know. Try to find out e.g. with xosview, which shows you
interupts...
