Hi Mihai, Not exactly related to disk speed, but have you cranked up the following sysctl to see if it helps?
sysctl kern.bufcachepercentage=9 I put an entry in /etc/sysctl.conf for persistence. This will cause up to 90% of system memory to be used as a unified buffer cache for disk access. Not sure if that helps but I use that value on every install, including desktop and servers. I can’t remember if the default value has changed in the past 10 years but I always go with 90%. -Brian > On Mar 7, 2022, at 6:17 AM, Mihai Popescu <mih...@gmail.com> wrote: > > On Mon, Mar 7, 2022 at 8:46 AM Janne Johansson <icepic...@gmail.com> wrote: >> >> Den sön 6 mars 2022 kl 16:41 skrev Mihai Popescu <mih...@gmail.com>: >>> >>> Since this thread is moving slowly in another direction, let me >> >> True >> >>> reiterate my situation again: I am running a browser (mostly chromium) >>> and the computer slows down on downloads.
