[Bug 1497678] Re: Ubuntu 15.10 beta is much slower to boot than 15.04

 

Can you please also attach a bootchart of 15.04? Otherwise we have
nothing to compare this against.

Indeed I/O really sucks -- most of the time it's between 2 and 10 MB/s,
and there's just a single peak at 23 MB/s. This would match what you'd
expect from a middle-aged rotational disk. There is virtually no CPU
utilization so everything hinges on the slow I/O. Do you still have
ureadahead installed? If not, can you give it a try?

Title:
  Ubuntu 15.10 beta is much slower to boot than 15.04

Status in systemd package in Ubuntu:
  Incomplete

Bug description:
  I'm attaching a bootchart. I'm not sure if the initrd time is included in this too? Because that could be the source of the additional time. But subjectively it feels about twice as long to boot as 15.04 on the same system. This is an upgrade from 15.04 to 15.10.
