Hi David, Thank you for your answer. The other OpenBSD:ers I talked to also used the wording "multiqueue". My understanding of the kernel's workings here is too limited. If I would give a reference to some implementation out there, I guess I would to the one introduced in Linux 3.13/3.16: "Linux Block IO: Introducing Multi-queue SSD Access on Multi-core Systems" http://kernel.dk/blk-mq.pdf "Linux Multi-Queue Block IO Queueing Mechanism (blk-mq)" https://www.thomas-krenn.com/en/wiki/Linux_Multi-Queue_Block_IO_Queueing_Mech anism_(blk-mq) "The multiqueue block layer" https://lwn.net/Articles/552904/ Looking forward a lot to your followup. Best regards, Mikael
