> 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
