Gutenprint isn't particularly fast; if your machine is slow, it may not
be able to run the printer at full speed. However, it should no longer
be pathologically slow -- in 5.0.0-rc2 and earlier, it ran at about 1/10
of its full speed.
If the resolution options offered list 2880x2880 and 5760x2880, then
you're using -rc2; if the options listed include 2880x1440 high quality
and 2880x1440 highest quality, you're definitely running -rc3.
There shouldn't be any conflicts between any of the 5.0 releases and any
of the 4.2 releases; if there are, I want to know about them.
It doesn't know anything about what profile you're using; it more or
less assumes something generally like sRGB input. I'd suggest using
1440x720 resolution (or Photo quality); the printer performs very well
indeed at that resolution and you'll get only minor benefits at higher
resolution.
