Hi! Any plans for multiqueueing in the disk/fs subsystem?
At least in the current absence of multiqueueing, my benchmarks (made on /dev/rsd0c) show that 16KB-aligned 16KB accesses are the fastest on the SSD:s I tested (recent Samsung SATA & NVME). http://undeadly.org/cgi?action=article&sid=20100417195756 tells there is indeed 4KB sector support internally. Based on my benchmarks, if I could up it to 16KB, I would do it. I will benchmark the filesystem in 4KB mode first though. Thanks, Tinker
