Performance

I don't know if this mail belongs here. Probably it should go to the
developers list. But I'm sending it anyway. I apologize for that. 

I'm working on a text mining application that extracts key words/phrases
from documents. I was using the jregex package in my application. It was
working fine, but it was taking a lot of time. Then I tried ORO. But
looks like ORO is taking even more time than jregex. I ran a profiler on
both the packages for 50 documents (Each document has around 1000 words
on the average). The ORO's regex package made around 119 million
invocations. That's a lot. The execution time was 35% more when I used
ORO instead of jregex. I'm attaching the outputs of the profiler for
both the packages. I was wondering if you guys can do any performance
optimizations.

Thanks,
Ravi.
