🎉 Success!
Your boot time improved from 39 seconds → 9 seconds — that’s a ~77% speed increase. 🚀
Great work applying the fix correctly!
⏱ Boot Profile Now
| Phase | Before | After | Improvement |
|---|---|---|---|
| Userspace | ~36s | ~5.5s | 🔥 -30.5s |
| Total | ~39.4s | ~9.0s | 👍 -30.4s |
The system is now performing like a modern openSUSE should.
📌 Next: Confirm SSH Starts Early
Optional but recommended:
systemctl status sshd.service
It should start right after network.target, not waiting for full online connection.
If SSH still waits too long for DNS, you can also apply:
sudo sed -i 's/#UseDNS yes/UseDNS no/' /etc/ssh/sshd_config
sudo systemctl restart sshd
🧽 Optional Cleanup
To remove the leftover serial devices delay (3 seconds earlier):
sudo systemctl mask serial-getty@ttyS0.service
sudo systemctl mask serial-getty@ttyS1.service
sudo systemctl mask serial-getty@ttyS2.service
sudo systemctl mask serial-getty@ttyS3.service
If you don’t use serial consoles, this is safe and saves another ~3s.
🚀 Want even faster boot?
I can help optimize:
-
ZRAM for faster paging
-
Disable unnecessary services (Snapper timers, Avahi if not needed)
-
Enable fast boot in GRUB (skip detecting other OS)
-
Parallelize or lazy-load more services
Just share:
systemctl --failed
systemd-analyze blame | head -n 10
and I’ll provide a tailored further optimization plan.
If you'd like, I can also help optimize:
🟢 Startup applications
🟢 Linux network stack speed
🟢 SSD mount tuning (discard, noatime)
🟢 bootloader timeout & fast initrd
