I have a GCC and a Xlc compile for AIX and there is hardly any difference 
at all in the POV times. If I remember correctly the skyvase scene took 
about 30 minutes on one of the machines I tried on about 2 years ago. The 
64 bit compile of 3.1 took just a bit longer (just a minute or two)

I have never really tried to run 3.5 on AIX nor have I tried to run 64 
bit code for a long time since the radiosity is broken on 64 bit 
compiles. :(

I haven't really tried to use a Power 4 or a Power 4+ machine yet, 
although we have several of them. But they are very fast indeed, 
unpacking a compressed file goes very quickly indeed.
