Need to improve throughput - Any thoughts

I have a text file with around 1 million lines and I need to do a search

And replace on over 9000 words. I am currently reading a line and
passing
A hash table against it and any matches it is replacing the word in the
string. It is running real slow. Any thoughts on how to improve it?
