generate-sea doesn't work very well. runtime can change from 1-3min per tile to 3-4hours. And I guess memory too. but didn't compare since the runtime problem was too much to continue. On 5 Oct 2009, at 24:52 , Du Plessis, Bennie wrote:
Hi,
I don’t know where to post a ticket, but I’m sure you’ll tell me if it’s the wrong forum.
Since version 1245 I had to increase the memory size in the MkGMap command line and the virtual memory of my machine to get mkGMap to work. (1245 was the last version I could get to work, but with the –index switch off)
What am I doing wrong or is my hardware just too small?
Did anyone else experience a large increase in memory resource usage since MDR & indexing was introduced?
I have not been able to test the results of the new dev around indexing yet, because I am not able to compile a map to send mapsource. It takes 3 hours to compile with these errors, so I can barely run 2 tries per night. If someone can save me time with some tips, I will sincerely appreciate it.
