I'm running Ubuntu 14.04, boot takes a long time. Attached is bootchart and dmesg log


dmesg text went over the character limit so I'm pasting a few time leaps:

[ 0.347842] Trying to unpack rootfs image as initramfs...

Googling these has me mostly confused. Would appreciate any thoughts

  • While I'm not knowledgable in reading dmesg output, here's what i found useful to increase boot speed, specifically refer to "Reduce Boot Menu Delay" part : howtogeek.com/115797/6-ways-to-speed-up-ubuntu – Sergiy Kolodyazhnyy Sep 22 '14 at 7:46
  • Is this a fresh install? Have you upgraded your system from 12.04 or some older version, and maybe several upgrades before that? – SPRBRN Sep 22 '14 at 7:47

I think a couple of minutes of boot time is a bit much than normal, but is still possible most than likely on some old machines. You didn't include your hardware configuration details, but the measured time is more than 115 sec, which makes me think that at least you have a hard drive disk in there not a solid state drive.

If you are looking for performance increase I would suggest upgrade/change your hard drive to SSD. It's not a tricky turn after all if you are not about purchasing a new computer.

Even having SSD drive in old machine will bring a performance increase because the device will not suffer with big time delays due to fragmentation.
