Benchmarking Sun X4100 using SiSoftware Sandra

Just had delivery of a new Sun Fire X4100 M2 with (2x AMD Opteron Model 2216, 4x1GB PC2-5300 DDR2-667 memory) and I thought I would test its performance compared to other machines. I decided that the best way is to install windows 2003 x86 on it and then use SiSoftware Sandra Lite XI SP2 (version 1135). The following diagrams are the results when Sandra was run from a remote PC session and windows fully patched (red show winner)

(a) Sun Fire X4100 M2
2x AMD Opteron Model 2216 @2.4Ghz,
4x1GB PC2-5300 DDR2-667 RAM

(b) Viglen
Intel Core 2 CPU 6600 @ 2.4GHz
2GB of RAM

(c) Xen/OpenSolaris
Using the Viglen above I installed OpenSolaris B78 with windows installed via Sun Xvm/Xen.
