Hi Stephane,<div>I think we should definitely profile this. Can you share a bit more details/reproducer?</div><div>In the past we've also relied on the internal performance team to get jfr recordings under proper load in a suitable bench environment. </div><div>Cheers <br><br>On Thursday, October 18, 2018, Stephane Epardaud <<a href="mailto:stef@epardaud.fr">stef@epardaud.fr</a>> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">

<p><font size="-1">Hi,</font></p>
<p><font size="-1">I was doing some benchmarks with gatling and came
across very strange results where if I have a REST endpoint with
normal result types I get 1200 requests per second, but if I
return those results inside RxJava's Single (with Single.just())
I get about 250 requests per second, and if I change that with
CompletionStage (using CompletableFuture.<wbr>completedFuture()) I
get about 310 requests per second.</font></p>
<p><font size="-1">Frankly I'm not sure how to go about finding out
why we have such a difference, and whether we can mitigate it,
but we should definitely try. How do you usually tackle these
problems? Any help?</font></p>
