I don't have any specific experience with Twisted on Sparc hardware, but one thing I'll point out is that Twisted is single threaded. Whether there are 4 cores or 8 probably won't make any noticable difference to a Twisted application's performance.
It looks like a single core on a T1000 is much less powerful than a single core in a Dell 2850, so this might account for some of the difference.

This is the conclusion we are coming to as well. We found a Dual Dual Core Opteron box with Solaris 10 x86 on it. The Opteron box was even faster than the Dual P4 box. So we have pretty much ruled out Solaris as the problem, everything points to sucky performance of the Sparc hardware.
