Hi,
if you are in favour of FreeBSD consider to test BusyBox with FreeBSD.
Tiny Core Linux is probably way faster than my bloated Arch Linux (not
using BusyBox) desktop install. I don't care about the startup time,
since the machine is usually up 24/7. Probably systemd is faster than
using init scripts.
[rocketmouse@archlinux ~]$ systemd-analyze
Startup finished in 2.653s (kernel) + 4.006s (userspace) = 6.660s
graphical.target reached after 3.619s in userspace.
[rocketmouse@archlinux ~]$ systemd-analyze blame | head
11min 38.519s fstrim.service
1.727s dev-sdc1.device
1.419s man-db.service
1.162s udisks2.service
696ms systemd-hwdb-update.service
614ms ldconfig.service
504ms systemd-random-seed.service
445ms systemd-udev-trigger.service
428ms accounts-daemon.service
389ms alice-dhcp.service
This is with a slow dual-core CPU and a bloated (realtime-patched)
kernel. The patch isn't the issue, but the kernel contains trillions of
modules I never ever will need, hence I could compile without those
modules. Right now I see that I even don't need all started services.
One of the slow services is udisks2.service, I guess I don't need it,
since I'm mounting by command line, not by mouse click.
[rocketmouse@archlinux ~]$ hwinfo --cpu --memory | grep -eModel -eSize | grep -v Main| sort -u
Memory Size: 15 GB
Model: 6.60.3 "Intel(R) Celeron(R) CPU G1840 @ 2.80GHz"
Regards,
Ralf
