Start up on Ubuntu 12.10 is much slower than on 12.04

Question

Start up toward login screen lasts about 40sec on both(12.10 and 12.04). This is good for me.

But after login, there is quite difference. System will start up in:

• Ubuntu 12.04: 10-13sec
• Ubuntu 12.10: at least 30sec

I have chromium in start up applications and this is the only non default app there. I also disabled some unneeded apps such as Bluetooth Manager, ... I also have installed preload.

Is there problem on my side or is the new Ubuntu slower in this way?

My PCs info:
Intel® Pentium(R) CPU G840 @ 2.80GHz × 2
GeForce GTS 450/PCIe/SSE2
Memory 3.9 GiB
Ubuntu 12.10 32-bit

Answer 1

For me it varies.

On some PCs the time is the same, on others the time for 12.10 is slightly faster. On a few, the time difference is noticeable (Like 10 to 15 seconds faster). This changes if I update the system. After upgrading 12.10, the changes is more noticeable for more PCs as 12.10 somehow speeds up.

What I would recommend would be to remove preload, Chromium and any other non-default changes you made. Then test both. Just a FYI, preload sometimes does not make the boot part faster. This varies on the hardware/software.

For 40 seconds of time, I would also suggest for you to add your hardware specs here. This could lead to better help.

Try installing Ubuntu 12.10 64-bit if your processor is 64-bit architecture. Actually I have a Laptop (Asus) with Ubuntu 12.10 64-bit and it runs faster than Ubuntu 12.04 LTS 64-bit.
