> I have a RouteOnContent step in my flow which performs a simple regex match with 2 outcomes (pass and unmatched).
> However, I noticed that it is spinning with a lot of empty task cycles when there is no data incoming at all. Moreover it causes 120% cpu usage spikes. Confirmed multiple times via top by simply stopping and starting RouteOnContent.
