From customer:
As part of our update testing (from GitLab 8.11.6-ee to 8.16.4-ee), I've noticed and interesting change in behaviour - particularly in the cache usage.
I've attached an image showing the sandbox Redis usage, with data pre and post the upgrade. As you can see, the number of cache misses has jumped incredibly significantly, and doubles again on the 13th of Feb around 1630 where I add another node to the cluster.
Can you let me know if this is expected usage? It's such a massive change in behaviour that it makes me slightly nervous about the update.
