the dialogue on PCI-X on FreeBSD vs. PCI-X on Linux:
& Hello,
&
& My company is currently comparing FreeBSD to Linux: specifically FreeBSD
& 4.11-RELEASE to Fedora Core 3.
&
& We're having a difficult time determining whether or not FreeBSD is
 utilizing & the higher speeds of the PCI-X bus.
My understanding is that it does.

The other thing I find interesting is that in my experience most "Linux" 
applications run faster on freebsd using linux emulation that they do on 
linux!  I think this may have something to do with differences in kernel 
overhead.. but you may need to speak to someone with greater technical 
knowlege than I for an explanation.

&
& Can anyone specifically state the status of PCI-X support in FreeBSD? The
& state of support in 5.X is fine too. This is a major issue as we determine
& which platform to move forward on.


&
& Note that I do mean PCI-X. I'm aware that PCI-Express is on Scott Long's
& wish-list of things to get implemented.
&
& Cheers,
& DMK
