17:20 semiosis pdurbin: to my great surprise i got worse performance from a ForkJoinPool implementation than a plain old thread pool  & queue
17:32 pdurbin good that you're measuring such things
17:33 pdurbin sounds like you expected better performance from fork/join
17:33 pdurbin but why do people object to Java 8's lambda/stream stuff being built on top of fork/join? is it a performance thing?
17:43 semiosis that one article you showed me was a performance complaint
17:44 semiosis which i thought was purely theoretical and didnt expect to see in practice, which is why i was surprised when the FJP was actaully slower
17:58 pdurbin see, I only give you good stuff to read
18:11 semiosis tyvm
18:36 pdurbin so does it scare you off from Java's lambda/stream stuff?
18:37 semiosis no
18:46 pdurbin me neither
19:05 semiosis if you need extreme single thread perf, probably not using java anyway
19:05 semiosis and besides, this is already about parallel workloads, so just scale out.

20:14 pdurbin yeah
20:15 pdurbin oh, there's also this: "Brian Goetz explains how lambda expressions are implemented using the invokedynamic instruction introduced in Java SE 7" http://www.infoq.com/presentations/lambda-invokedynamic
20:23 semiosis cool
