Post Feed very very slow?

[footyman]

I put a 'post feed' on the sidebar, to effectively replace my old 'latest posts' plugin from 3.4.6

The problem is that it doesn't seem to be updating very quickly at all, in fact somebody just posted something and it took literally 5 minutes to update with that post. 

I'm a bit cheesed off as I sought assurances that 4.0 has the functionality to have a 'latest posts' thing on the sidebar. 

Is there a way to make this faster, like update every 30 seconds or something?

Widgets are cached. The minimum is 60 secs. Look under General-Advanced Configuration. It's probably set to 300 by default.

Thanks, found it.
