have to correct myself (from my readme):

'The -current builds for sparc from October 7th, 2005, are built with 
-O4, the SuperSPARC iso got an additional -mcpu=supersparc.'

that felt much more when initiating ssh sessions from outside the 
machine... time to get it running again, to deliver some 'hard data' on 
this ;)

yip. i have a bunch of sgis here. not intending to start an off-port 
discussion, the MIPS machines /feel/ much faster than any (comparable, 
at least this is what the appropriate vendor's datasheet says) USII 
based machine, as my U2E. especially wrt Octane.

well, yes, i like seeing progress on the port-prep and related ports. i 
like PowerPC ;)
