ideally you don't have to (since it makes the lookups slow). This
would be the concept of grouping keys and values together, putting
them into various buckets, to decrease the ETS usage but increase
the binary size.<br>

Tony,
Wow, 48-bytes is a huge overhead as N ~= 1000, and Every reader reads a binary 10x times or so per second.
Can anyone please suggest a better strategy to efficiently share them with a lesser overhead?
Frank.

1. A reference.
It will however build a 6-word structure called ProcBin on the heap for every binary reference that you read.
On a 64 bit machine that will lead to a 48 byte overhead. Nearly 10%.

Hi guys
Suppose an ETS table with only 1 writer and N readers
This table contains only large binaries (>64B) with the same size 512B exactly.
The single writer update these Bins once a while.
The N readers regularly read one of these Bins, but never change/update them.
Questions: what a reader gets when reading a Bin from this ETS table:
1. a reference to that Bin
2. or a full copy of that Bin
Hope someone can clarify this (with an example).
Thank you
Frank
