Clear message

Reference platform

All tests and charts were done on a Dell Mini 10v, with an 1.6 GHz dual core Atom CPU (i. e. rather slow), and a 16 GB SSD with a maximum read throughput of ~ 96 MB/s (according to palimpsest, confirmed by ureadahead bootcharts).

Boot charts apply to a stock Ubuntu install with autologin enabled, unless otherwise noted.

Boot times

Rounded to .5 s; note that the numbers do not add up perfectly, as the phases overlap, and there is always some inevitable noise.

Click headers for boot charts.
