Loader I/O performance is much better these days so loading modules pre-boot doesn't slow the boot down much any more, but it's still more than zero, and it still increases low memory fragmentation, and you still can't unload a module that was loaded pre-boot. > and that the preferred way is to load everything from loader.conf. I suspect you're extrapolating here. There is a very small number of cases where loading pre-boot is required (e.g. zfs.ko if your root is on zfs) or recommended (e.g. USB HID drivers due to probe ordering issues) but in the majority of cases, it is still better (even if only slightly) to wait until after boot.
