In gstat the default display of operation/ms is only one digit after the comma and there are a lot of R/W operation displayed with the 0.1 value on my SSDs. This simple patch displays the operation/ms with two decimal digit. The file gstat.c.patch is for 11-CURRENT, but you may prefer to build it. ####Build:
pkg install git
git clone https://github.com/maurizio-emmex/gstat_freebsd
cd gstat_freebsd
make install
