R help - Jul 2007 - speed up crr function in cmprsk package

I am trying to use the crr function in the cmprsk package to analyze a large
patient dataset (45000 +), The model has 100 + covariates and 5 competing
risks. I am finding that R seems to get bogged down and even if I let it run
for several hours I don't get anything back. Am I expecting too much, or are
there ways to speed up the process? Any help is appreciated.

Best,

Spencer
