oob min/max thread doesn't work when oob_thread_pool_queue_enabled = true -------------------------------------------------------------------------- Key: JGRP-2016 URL: https://issues.jboss.org/browse/JGRP-2016 Project: JGroups Issue Type: Enhancement Affects Versions: 3.6.7 Environment: Linux 3.19.0-25-generic #26~14.04.1-Ubuntu SMP Fri Jul 24 21:16:20 UTC 2015 x86_64 x86_64 x86_64 GNU/Linux java version "1.7.0_80" Java(TM) SE Runtime Environment (build 1.7.0_80-b15) Java HotSpot(TM) 64-Bit Server VM (build 24.80-b11, mixed mode) Reporter: rama rama Assignee: Bela Ban Priority: Critical hello, i have noticed that setting oob_thread_pool_min_threads = 10 oob_thread_pool_max_threads = 100 oob_thread_pool_queue_enabled = true doesn't create new thread (up to 100) but keep thread number at 10 and queue items before spawning new threads. i think that the same behavioud apply to thread_pool_queue_enabled = true What is going to block me, it's that if i set 100 threads, i expect to get higher concurrency rather than using queue, and use queue AFTER having finished the max_thread. in that way the concurrency seem to get limited, am i wrong? as a workaround i can set 100 as min thread, but seems to waste quite a lot of resource and ctx switch if my working scenario is just to handle spikes of load every time to time (and on the same server i was thinking of running more application that use the same idea, having all of them create 100 threads sound unhealty) forgive my terrible english, any feedback is appreciated
