Thanks a lot.
That my example was not good.

1.6.1 (GENERIC) on my Classic II ('030/16MHz, 10MB RAM, with FPU) takes
more than 5min 30sec for booting up. (from "Boot Now" to "login:")
It gets slowdown after the line "root file system type: ffs", especially
it's very slow at:

Building databases...
Starting syslogd.
Checking for core dump...
save core: no core dump
Mounting all filesystems...
Clearing /tmp.
Creating a.out runtime link editor directory cache.
Checking quotas: done.
Starting virecover.
starting local daemons:.
Updating motd.

Can we control those things with kernel configuration? I don't think so.
That is the reason I used the word "userland".

I'm sorry, no difference is found. (an error is less than 1sec.)

vm.execmin=5          5' 36.38"    5' 36.57"
vm.execmin=8          5' 37.07"    5' 36.25"
vm.execmin=10        5' 37.15"    5' 37.19"
vm.execmin=15        5' 37.37"    5' 37.00"
vm.execmin=20        5' 36.96"    5' 37.46"

Why? Do you have any idea what I did misunderstanding?


Learning NetBSD is very interesting ! Many thanks to all,
