/commented by dmitriy setrakyan/ As I suggested before, I believe Ignite already utilizes all the Cores, so if you try to do something additional in parallel, you are essentially beginning to compete with Ignite jobs.
To check that, look at your Core utilization when you are NOT using parallel streams and see if all the cores are utilized by Ignite. If yes, then parallel streams will only slow it down because they will add thread contention. ----- /This post is migrated from now discontinued Apache Ignite forum at http://apacheignite.readme.io/v1.0/discuss/ -- View this message in context: http://apache-ignite-users.70518.x6.nabble.com/Perfomance-Java-8-lambdas-tp70p76.html Sent from the Apache Ignite Users mailing list archive at Nabble.com.
