I can tell than an O2K with 64 CPUS works quite well when the hardware
isn't failing, but the hardware is often failing...

Linux 2.1.* is very preemtible, even if there are stil some things to

xfs is _very_ good.

Interesting. Our "local" SGI vendor (i.e. the one for France), told
us that 1GB/sec write speed was too much and he could only guarantee
800MB/sec for our 1TB raid array.

The limit on x86 is 2GB. To be fair, said terabyte files and
filesystems are connected to systems with a 64bits architecture.
Afaik, linux on alpha handles terabytes files.
