Faster: reg mem[] or M9K?

I'm not meeting timing on my design. It takes over 8ns to pull data out of a 'reg' based 128 deep mem[] (see attached Timequest report). I'm considering ways to speed things up and use of M9K blocks ...

FYI: I ended up using a Megawizard-generated 2-port altsyncram module backed by M9K blocks. This works very well.

Thanks.
