Hi,
One question: Do you seed the whole world or only BBOX of Germany? Resolution
of level 17 is 1.1943 m and Germany is not a big country which makes me feel
that 21 days is rather a long time. I have seeded the area of Finland to 0.5 m
resolution from aerial images into 2 TB of tiles in about the same time which
makes me feel that one week should be enough for you. However, I was seeding
from an external WMS and you most probably have different hardware so our
situations are not comparable.
I would absolutely divide the job into a bunch of smaller BBOXes. I have a
feeling that the Seed missing tiles option is not always reliable but it can
wrongly think that there is nothing more to seed. However, if you have been
seeding for two weeks and all processes die it is not really reasonable to use
the Reseed option. If a small job interrupts it does not pay so much to start
it again.
Follow also the CPU load. Adding more seeding processed after the load is
already close to 100% makes the overall speed just slower.

Hi,
I have a 100MB shapefile with LINESTRINGs covering Germany, which I added as a
cached layer. I use GeoServer 2.6.2 with included GeoWebCache 1.6.1 to seed
tiles for layers 0-17 for the predefined EPSG_900913 gridset. On a server with
8 cores this process takes about 21 days.
I use Oracle Java 7 and JAI is installed. I've set "Number of tasks to use" to
8 (number of cpu cores).
Is there anything I can do to speed up the seeding process?
Best regards,
Jens
