I am curious about how much cost for both cpu and memory when automatic
refresh is on while I am not adding new index. For example, when it is time
to refresh, ES have to look at the buffer to see if there is anything to
refresh. how much would this cost even there nothing to flush.
Thanks,

The cost of automatic refresh if you haven't written anything is pretty
close to 0. I believe elasticsearch keeps a list of all indexes that have
been written to rather than checking each one.
