I've been running this now with caption only, and I'm surprised how fast it is.
I've changed the BorderNS to 0.3 and BorderWE to 1 (I've had a look and I don't
think more than 1 degree is necessary).
I get an average of just over 1 minute per tile so far, and it is at x 14
(that's midwest USA: Sioux Falls, Omaha, Denton).
Slowest tiles were 6/10/24 and 6/10/25 at 13 and 15 minutes, that's around LA
and there are a lot of captions there, and the most prominent doesn't get picked
by the renderer. Maybe someone has to edit the name tag for LA to make it the
first to be picked.
Simple sea-only tiles get rendered in 45 seconds.
All this is on an AMD Athlon X2 5050e with 4GB of memory.
Regards,
Maarten
