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.
