If you post your conf I can give you pointers on InnoDB performance.
Please also post a hardware profile (including ram and IO hardware).
One way or another this is the right first step for a comparison with
PG.

As for tokutek, I think they are probably the wave of the future. I
have suggested that they create a pg product.
