<div dir="ltr">Hello!<div><br></div><div>I have about 100 nodes in cluster, each node in cluster contains about 100000 elements in proplist. All proplists have equal length, the same keys, but different values. I need to get the sum values for every key between all proplists. By example, it can be represented as matrix NxM (N~=100, M~=100000), and I need to get the sum by column. </div><div><br></div><div>The problem is that it's too slow, even when I use the hackish way with ets:update_counter and N=2, it's take about 1.5 secs, If I make in parallel, it's take about 2-3 seconds.</div><div><br></div><div>How can I make it fast and efficient?</div><div><br></div><div>-- <br><div class="gmail_signature"><div dir="ltr">Петровский Александр / Alexander Petrovsky,<br><br>Skype: askjuise<br><div>Phone: +7 914 8 820 815<div><br></div></div></div></div>
