Hmmm. In Linux there is the vm.swapiness parameter that dictates how the vm should prioritise swapping. Although not perfect, is there a similar tuneable available in FreeBSD? I think it would be useful to be able to tune this as different workloads will benefit from different settings. The parameters I’m aware of are: vm.swap_idle_enabled: 0 vm.defer_swapspace_pageouts: 0 I haven’t tried these parameters in FreeBSD 10 yet… have anyone else seen the impact of these? Cheers Johanhelp
