Caching frontpage (latest posts)

Hi there

Is there any way to cache a front page that shows “latest posts” (and not static page) ?
We only do 2 posts a day but the query requires quite a bit of cpu time for the thousands of people coming in each day.

Right now it seems like this isn’t cached (everything else is). It would be great to keep it in memory for a couple of hours at the very least.

Thank you!
