Hi Ray,
If you are not using CAS then disabling it can help, see [1]. Also
depending on your 'stats slabs' you may want to tweak the minimum item size
and growth factor to try and get the slabs to more closely match the size
distribution of your items. Check the 'Unused Memory' graph in AWS, if it
is high and you are still seeing evictions then you may benefit from
adjusting the item size configurations before increasing node size or
adding nodes.
