title: Is there any Redis pub\sub benchmarks?
body: <p>I have found this <a href="http://redis.io/topics/benchmarks" rel="noreferrer">topic</a> benchmarking almost all the important Redis commands but it doesn't include PUB\SUB benchmarking. I would like to know something like how much time on average is consumed from the time a key gets created, deleted or expired and the notifications is received by the client for these event?</p>
  
  <p>Also according to <a href="http://redis.io/topics/notifications" rel="noreferrer">keyspace notifications</a> in section (<strong>Timing of expired events</strong>) explaining that there could be a delay in the certain keys expired notifications if (1) I am not accessing these keys frequently, or (2) there are a lot of keys with TTL in the cache.</p>
