Compared to the last 2.2 point releases this one compares quite a few potential performance improvments: * for ZVOL workloads (relevant for qemu guests) multiple taskq were introduced [1] - this change is active by default (can be put back to the old behavior with explicitly setting `zvol_num_taskqs=1` * the interface for ZFS submitting operations to the kernel's block layer was augmented to better deal with split-pages [2] - which should also improve performance, and prevent unaligned writes which are rejected by e.g. the SCSI subsystem. - The default remains with the current code (`zfs_vdev_disk_classic=0` turns on the 'new' behavior...) * Speculative prefetching was improved [3], which introduced not kstats, which are reported by`arc_summary` and `arcstat`, as before with the MRU/MFU additions there was not guard for running the new user-space with an old kernel resulting in Python exceptions of both tools. I adapted the patch where Thomas fixed that back in the 2.1 release times. - sending as separate patch for easier review - and I hope it's ok that I dropped the S-o-b tag (as it's changed code) - glad to resend it, if this should be adapted.
