Hello Bowen, Jon,
Thank you for your answers.
I will continue investigating following your advice, currently there is no
performance issue, and we have good HW etc, so probably no need to optimize
caches.
Have a good day,
Sébastien.

I haven't found chunk cache to be particularly useful. It's a fairly small
cache that could only help when you're dealing with a small hot dataset. I
wouldn't bother increasing memory for it.
Key cache can be helpful, but it depends on the workload. I generally
recommend optimizing for your
Hi Sebastien,
What's your goal? Improving cache hit rate purely for the sake of having
a higher hit rate is rarely a good goal, because higher cache hit rate
doesn't always mean faster operations.
Do you have specific issues with performance? If so, can you please tell
us more about it?
