I'm very much less of a x86 lover (otherwise, I won't be using a Sun
workstation instead of a cheap WalMart PC with Lindows (:
I also know that my U10 can't be rocket fast like a new SunBlade, but
currently I'm experiencing some difficulties getting some activities done.
I'll try to use external SCSI disks in order to offload the CPU from the hard
work of managing an IDE controller that isn't capable of Ultra DMA (even if
my workstation was shipped with two Ultra DMA Seagate drives). Most of my
everyday activities include software compilation and movie playback, and I
just would like to render my box able to do this in a timely fashion.
I haven't the possibility to get a more performing video card, so I'll try to
optimize my current hardware (I'm about to add a 256-Mb RAM expension) and my
current software, that is basically Debian Gnu/Linux. I already set up
production machines with Debian on Sparc in my corporate environment and both
me and my company are completely satisfied with the achieved results.
Moreover, as I posted before, I noted some strange messages in the kernel
while playing video files.. maybe solving this issue may be the silver
bullet, combined with the adoption of SCSI drives.

At the moment, I can only say, with a reasonable amount of background, that
the system is slow during video decoding (MPEGx at least) probably due to DMA
issues between the IDE controller and the PCI integrated video controller.
I'll surely investigate more in the future.
