Yeah, default is 1.25. We can certainly start with 1.25.
Thanks again,

Hi,
The engine version we have running right now is 1.5.16. I just saw an
announcement that 1.6.6 is available, so we’ll probably plan to migrate.
Adjusting growth factor makes sense. I did a quick google and don’t see any
definitive formula to calculate an appropriate number. I’ll probably
1.5.what?
also yes, chunk_size_growth_factor. don't set it to 1.02. set it to
something so your slab classes are more evenly distributed. the max is 63.

Unfortunately when it comes to elasticache the answer is probably to just

newer verisons do a lot better at balancing memory.
This is also suspect:

session keys being evicted before TTL even though the cluster seems to have
ample free memory, which hints at slab imbalance. I've included a print
