Stratix III MLABs are slow

Hi, has anyone here any experience (like me) with Stratix III MLABs? They seem slow i.e. my design fmax seems limited by MLABs more than anythings else. I have all the timing constraints require...

I tried the logic lock region but it didn't constrain the memory to a very tight area and still failed to meet timing by a tad. I'm now attempting to constrain the logic lock region manually, but it's not a very convenient way to do things as I have a lot of MLAB based memories.

If I have say a 272X8 memory in MLAB, would it be better to constrain the logic lock region as 1X17 or 17X1 or 5X4 etc. Any ideas?

Has anyone else had MLAB problems?

Many thanks,
