So you are right the IDE does give better performance but the SCSI SATA does need to be enabled. I Think ;\ Now I am trying to iptables working, then SELinux Thanks Shaun Jeff Garzik wrote: > On Mon, Oct 27, 2003 at 01:08:46PM -0500, Bob Johnson wrote: > >>-----BEGIN PGP SIGNED MESSAGE----- >>Hash: SHA1 >> >>The Sata driver worked well on my siimage, but lost around 30%-40% performance >>according to tiobench. > > > This is to be expected -- I use a "sledgehammer fix" for the Maxtor and > Seagate errata -- each transfer is limited to 15 sectors. > > When I get a chance to clean up the SiI driver, the performance will > indeed increase by a large amount. > > For now, for Silicon Image, I recommend using the > drivers/ide/pci/siimage.c -- assuming it works for you, of course. > > The libata Silicon Image driver is marked with CONFIG_BROKEN because it > is fairly easy to lock it up (I need ack some more interrupts). > > Jeff > > > >
