F95 vectorization support

[ASIF LAKHANY]

Recently I have been involved in mixed language programming on Solaris 
sparc/x86 using Sun CC. I clearly see amazing performance improvements 
when off-loading mathematically
intensive code to F95. I am new to F95. I generally develop in C++.
 From what I see it looks that gfortran may not provide anything beyond 
what g++ would
provide. Is the compiler sensitive to vectorization supported by F95?
It is very essential for me to know this as I rather not offload 
calculations if there is
no gain whatsoever.

Thanks for the support.
