So I was unable to run the latest speed tests on the Linux 64bit live CD that works on my Q9550 since it only contains Python 2.5 but I did get a chance to run some benchmarks one of my GMP programs so we have some real-world tests on a subset of MPIR. You can see a very nice progression from MPIR 0.9.0 to the almost 1.0 code (SVN 1728). I was expecting a big change in Core2 code but I was also surprised to see the AMD64 code got a nice speed jump since 0.9.0 as well.
