Google Caffeine and Autoblogging Questions

With google caffeine now implemented in nearly all of the google servers are we going to see a gain or drop in the indexes for our autoblogs ?

A couple of thoughts ... I have heard page loading time is now a major factor which means free hosting is not going to be a realistic option anymore. It also means less plugins is better as this will decrease page load time.

I have also read that google caffeine now penalises for duplicate content. I understand duplicate content was not a problem before but it might be now. Anyone comment on this ?

Any comments welcome.

WP Super Cache should help your response times a bit.
