Subtables, performance and resouces

Hi,   I know that subtables should be be used sparingly because each subtable is pinned to TMM instance that created subtable - so it's using RAM of this TMM - could create uneven RAM consumption...

Hi Piotr,

if the stored cookie values are not that big (e.g. ~50bytes) then it wouldn't be a big deal. It should consume just a few Mbytes in total.

To see the resulting RAM consumption of 50.000 keys you may want to use a "while" loop to create 50.000 dummy keys and then measure the resulting memory consumption using.

tmsh show /sys tmm-info

Cheers, Kai
