I think posing the question in such an open way is not likely to get you 
the response you are looking for...

What I would suggest is as my (and Roberts) previous email - yes 
continue to investigate the backend end code, but try and look less for 
a big bang solution and start by working with the current architecture 
and try to start by simply optimising.  I think in the first instance 
you will learn a bunch about where the blockages are and why - this in 
turn will help coding up larger changes should they be necessary.

I definitely think there is a risk of premature optimisation here and 
that the slowdowns are possibly not where you think they are?

Do please continue to investigate though - I think start by 
instrumenting the code and show the exact timings of each stage of the 
code - you can use this to help show where improvements could be made - 
others will likely also help with ideas to make these speedups?

Good luck
