You read it correctly.
But please see the caveat at the table end.
Do they both use Debian Wheezy guest? You have a remark that ppc64 has
problems with its clock. Was it taken into account when the slowdown
factors were calculated?
The time of a job is computed as the difference between a time stamp
made by the test system and the report time. The first time is affected
by ppc64's slow clock, the latter is correct.
A cron job sets the clock every 30 minutes, so the ppc time might be
*overestimated* < 30 minutes.
