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)
