Which Powerpc processor did you use?
eX00?

Ok, nice, was thinking of maybe getting something like this for the lab.
But buying old equipment for Ericsson is difficult. :-)

Finding someone to donate it might be easier. ;)

Actually managed to find out how to buy stuff second-hand. We've bought
a dual-processor Powermac G4 1.25 Ghz.

Should be good for testing UST and LTTng performance as well, all these
years after 32-bit PowerPC was abandoned by Apple the embedded space
still has only about this performance.

Ericsson has started going multicore with PPC now so I think it's  
relevant to
do some testing on it. Especially to check what performance impact UST  
has
assuming that one core is doing realtime while being traced.
