The first boot is slower because all the manifests for the system
services are being loaded in for the first time. However, the amount
of RAM also has a great impact on the speed OpenIndiana runs at, and I
won't suggest to run it with less than 2 GB, if you want to use it for
anything. This is in part because ZFS likes to cache as much as it can
in RAM, but will not be able to if the RAM is taken up by the rest of
the system.
