Without this tuning, the sy= stem remained very slow for a few seconds. However, even a halving vfs.zfs.arc_max and vm.max_wired, did not solve the problem in my case. Also, if i suspend memory absorption on (vm.stats.vm.v_laundry_count * vm.stats.vm.v_page_size) > 10M the system does not kill processes, and can not purge laundry pages to swap. Probably there is some kind of deadlock or other similar problem.
