the ia64 port of mono has very few users, so it is not very optimized. In this
particular case, Sin is probably implemented directly by using a SSE/MMX
instruction on x86, while it is implemented by calling a library routine on
ia64. If you need performance, you should probably avoid implementing
perf-critical parts in C#, and do it in C/C++ with pinvoke, or use java, which
as I heard has pretty good performance on ia64.
