Well... the SGI WD33C93 SCSI driver in Linux isn't as efficient as it
could be... so at best, you can usually only expect up to about 3MB/sec
transfer rates from the local disk... and that's on a good day. IRIX
has a significant edge there for obvious reasons.
I spose, one plus in IRIX's favour is that all SGI hardware is
supported... which isn't the case in Linux. VINO for instance, barely
works in Linux... and the WD33C95A SCSI controller present in Challenge
S machines, does not work at all. (And is unlikely to ever work --
apparently it's one nasty beast to work with)
IRIX 6.5 also is fully 64-bit... using mostly n32 binaries (32-bit
binary with some 64-bit extensions), and a few o32 (pure 32-bit) and n64
(pure 64-bit) thrown in where appropriate. Linux on an Indy generally
uses a 32-bit kernel and o32 binaries unless you specifically compile it
as 64-bit.
Linux can run a 64-bit kernel (and does by default on the Indigo2
Impact, Octane Origin and O2 systems), and, depending on the system,
will run quite stable. 64-bit Userland support in Linux though,
however, is very touch and go. n32 works... but only just. I wouldn't
recommend it for production use... and n64 is totally untested in Gentoo.
So IRIX theoretically should be faster than Linux... but these days...
if you were interested in speed, you wouldn't be using an Indy anyways. ;-)
