Hi all,

my friend started using of OpenBSD on his server, but he has quite bad
perfomance with his disk. Actually it's running under native mode :

pciide1 at pci0 dev 31 function 2 "Intel 82801EB SATA" rev 0x02: DMA,
channel 0 configured to native-PCI, channel 1 configured to native-PCI
pciide1: using apic 2 int 18 (irq 9) for native-PCI interrupt


and there is no chance to switch it to AHCI. So he will install newer
BIOS (there is no info about possible new option for it in release
notes). So before additional tests it will be ok if it will be
possible to switch to AHCI directly. Is there this option? From man
page for pciide I can see that it's possible to set some options for
some controllers over config so is it possible for AHCI too? Soft
updates aren't enabled and I know that it will have impact on
performance so he will enable it. Then it's only on AHCI/native, namei
cache and combination of all HW involved.

This system is definitely too old for AHCI to be a chipset option.  

You could always add in a cheap SATA card with Silicon Image chip, the sili driver supports NCQ...

1-3MB/sec isn't near the max speed of any of your hardware, and you fail to mention what you are doing while iostat is running to show this.  What is the problem again?

Moreover, it might possibly be that Eurasia and Eastasia are fabrications, and that Oceania is the sole world power. In such ambiguity is the meaning of perpetual war: internal subjugation disguised as defence against foreign subjugation, the theory and practice of oligarchical collectivism..."

Ok just small update. Friend enabled Soft Updates and there is quite
better speed now. What's is the real problem is Dolphin from KDE. In
Dolphin he can copy to another place in his LAN only about 3MB/s. With
scp in console or terminal under KDE he is able to get about 11MB/s.
BTW he tried to copy 2.4GB iso file from his laptop to server and
backward.
