For Rails, I think there are some configuration options you can  
fiddle with - but as you know, twiddling the knobs on the front of  
the server (so to speak) is less likely to produce a significant gain  
compared to re-writing the algorithm in a lower-level language, or if  
the algorithm is wasteful, tuning that.  I'd suggest looking at the  
RailsExpress [1] website - dedicated to tuning Rails apps, and/or  
posting time critical pieces of code here (if that option is  
available due to confidentiality restrictions).  Many of the people  
here will have a lot more experience of ruby than yourself (as you  
mention that this is your first ruby application), and may see a way  
of squeezing some extra performance out of the code without a C re- 
write.  I discovered when I first started ruby that there are many  
ways to achieve the same goal, but some of them use a hell of a lot  
less processing power than the others - an example was on this list  
just a couple of weeks ago regarding Blocks and Procs [2].  Hope  
these suggestions help.

Thanks

Kev
