[Bug 570805] Re: [regression] dpkg fsync cause massive regression in Ubuntu Server and Alternate installation times

[Roel van Os]

Using the testing method from #17 for the package oxygen-icon-theme
(5890 mostly small files), tested on a 5400 RPM laptop harddisk
formatted with ext4.

  dpkg 1.15.5.6ubuntu4:
    unpack: 37s
    real: 53s

  dpkg 1.15.5.6ubuntu5~ppa1:
    unpack: 5s
    real: 22s

Also tested on a RAID 0 array consisting of two 7200 RPM desktop drives,
formatted with XFS:

  dpkg 1.15.5.6ubuntu4:
    unpack: 56s
    real: 53s

  dpkg 1.15.5.6ubuntu5~ppa1:
    unpack: 13s
    real: 21s

So quite a noticable difference in both cases :-)
