Meta Stack Exchange is where users like you discuss bugs, features, and support issues that affect the software powering all 157 Stack Exchange communities.

What is meta?
Here's how it works:
  1. Any Stack Exchange user can ask a question
  2. The community provides support, votes on ideas, and reports bugs
  3. Your voice helps shape the way Stack Exchange operates

The Newest tab is cached for 2 minutes. This means that if a new question is posted, it may not appear for up to 2 minutes.

Is there a way to increase the cache time, but invalidate the cache immediately when a new question is posted? This way:

  • Users get their answers faster
  • People spamming F5 won't suddenly find 4 new questions they want to answer at the same time
  • It's unlikely to be a performance problem for the server (even if a new question is posted every 20 seconds, generating 3 lists per minute is nothing)

In addition to your suggestions, I would like my brain implant updated in real-time, so I don't have to keep my cybernetic finger on the F5 key all the time. – Robert Harvey Jan 29 '10 at 17:07
    
so... you want to encourage people spamming F5?? – quack quixote Jan 29 '10 at 17:13
    
Managing distributed caches is not as trivial as it may look on the surface (unless you're using things like memcached). – xmm0 Jan 29 '10 at 18:21

Spamming F5? Man, "spam" is applied to just about everything today. I'm going back to my self-imposed Monty Python marathon. – Robert Cartaino Jan 29 '10 at 19:00
