Done! The url is the same. The new benchmarks improve speed for ublas by using noalias(A) = prod(B, C) but the kmatrix speed is still far superior on my machine. (celeron 1.6, yadda yadda yadda)
Did you try to compare kmatrix with
ublas::matrix<T, row_major, ublas::bounded_array<T, M*N> >;

Just did, basically the same results: comparing integer matricies 2,2 X 2,2 kmatrix 63 msec elapsed ublas 156 msec elapsed 3,3 X 3,3 kmatrix 219 msec elapsed ublas 438 msec elapsed 100,100 X 100,100 kmatrix 406 msec elapsed ublas 1187 msec elapsed 100,1 X 1,100 kmatrix 125 msec elapsed ublas 203 msec elapsed 1,100 X 100, 1 kmatrix 406 msec elapsed ublas 1172 msec elapsed comparing double matricies 2,2 X 2,2 kmatrix 78 msec elapsed ublas 172 msec elapsed 3,3 X 3,3 kmatrix 219 msec elapsed ublas 469 msec elapsed 100,100 X 100,100 kmatrix 547 msec elapsed ublas 1390 msec elapsed 100,1 X 1,100 kmatrix 156 msec elapsed ublas 219 msec elapsed 1,100 X 100, 1 kmatrix 484 msec elapsed ublas 1375 msec elapsed - Christopher Diggins
