well, I don't know exactly why, but it gave with me a speeding up of about 10%

I'll try it out and see if renders faster.

It should work fine. Just don't use +SPxx when you continue rendering. What I
don't understand is why you used SPxx at all... this is for preview only, there
is no reason in using that for the final rendering. POV also will not use pixel
which were rendered in the preview process for the final step! ... so if for
example your picture is still at 2x2 preview rendering and you see that you will
want it at final resolution you better stop it and start again (except you have a
HUGE parsing time.)
