--- Comment #3 from Konstantin Belousov <kib@FreeBSD.org> ---
Could you try the same load on your machine, with e.g. swap-backed md(4),
formatted into UFS with same tuning (AKA tunefs(8)) ?  Is slow-down
reproducable ?

If not, I wonder if you can replace your disk by different model and try the
same load.
