[trimmed cc] on 27/05/2013 15:29 Orit Moskovich said the following: >>From what I've read in subr_taskqueue.c taskqueue_swi, taskqueue_swi_giant and taskqueue_fast are all implemented using swi_add which calls ithread_create(). > Is there any performance difference between them. Is one of the above or ithread given to bus_setup_intr preferable on the other? The differences are described in taskqueue(9) "Predefined Task Queues" section. -- Andriy Gapon
