[ublas] matrix vs. c_matrix performance

I've run a couple benchmarks to compare (dense) matrix vs. c_matrix, doing a simple

matrix_type<T,M,R> A;
matrix_type<T,R,N> B;
matrix_type<T,M,N> C;

noalias(C) = prod(A,B)

My benchmarks indicate that c_matrix is slower than matrix! Is this normal? I'm 
using boost cvs head and vc8.
