Any performance numbers for VMS on X86_64 are not *that* interesting until it's 
built with native optimizing compilers.

Native compilers are becoming available, but the build process will take some 
time to convert to a native build.

I do not think (but am not sure) that V9.2-2 (scheduled for near the end of the 
year) would be a native build.  Early builds of that version are being done
with cross compilers.
