[erlang-questions] ets:update_counter/3 optimal settings

Hi Everyone,

I've some troubles to understand the optimal settings for this little
simple problem:

Two Erlang processes A and B.

1. Process A randomly increments a counter during its lifetime using "ets

2. Process B reads the counter every X seconds and reset it to 0.

I decided to use these options when creating the table:

{write_concurrency, true}, %% A and B
{read_concurrency, false}  %% only B

Are these settings correct and more importantly "optimal" (please elaborate
your answer)?
