Re: stl vector slower than pointer access

[ufnoise]

Well it appears that the original code runs much faster on gcc-4.0.3
and gcc-3.4.4 than on our compilation of gcc-4.1.0.  In fact the stl
array access is slightly faster than the pointer array access.

Very suprising.  Thanks for everyone's response.
