What does it meen when refresh rate is high?

Using 1.4.3

So I have a nice "beefy" cluster 4 nodes of 32 cores, 128GB RAM, 5TB RAID 0
(Using Sandisk 960GB Extreme Pro) for each machine.

I am indexing about 4000 documents per second at an average of about 800
bytes per document. At the same time as indexing I'm running queries.

Looking at Elastic HQ numbers.

    the refresh rate has always been red... What does it mean and does it
