> A possible explanation might be that in our case consumers were reading
old pages while producers were writing new pages. There is no intersection
between these two groups such as a common page being writing&reading by both of
them.
So why it the consumer side is being slowed down?
I need to check, but I remember that consumers were querying the live page
cache, but I could be wrong.---
