Well I did cache the page for each user, because most of the content
on a site isn't that dynamic that has to be reloaded every second.
Should content on a page change you invalid them for everyone. Even if
the cache is for short period it's worth it.

How: I used CacheFu and the description there.

Well this is a problem, here you have something that invalidates the
page every second or at least minut, but still caching one minute is
worth alot on an active site. There are probably ways to do this with
JS so it's on the client side instead but then you can't be 100% that
it's the same time as on server but it shouldn't diff that much if you
initiate the JS with right time.

If your dynamic parts are not to complicated I would consider Squid3 and ESI.
