I have been using NetNewsWire since I began reading blogs. The trouble is that it is WAY SLOW. Does anyone have a not slow client side mac RSS reader they like?

I can't stand what I have now it takes like 5 seconds to move from one post to the next. I know I have a lot of posts - cause I am keeping way more posts then I actually read. I do this cause so far there are not good engines that let me search small slices of the blogosphere well. So saving them on my computer seems like the way through.
