I am trying to import whole planet data to my i7 3770k + postgres on SSD + 16gb RAM in order to render my custom tiles.
But the process is painfully slow and multi core is not helping (though you have specified)
osm2pgsql -d planet -U osm --slim -C 8000 --number-process 4 planet-120704.osm.bz2
htop what I can see is osm2pgsql take 100% of 1 core and postgres takes only 10% of cpu.
and current prompt is:
Processing: Node(208320k 147.0k/s) Way(0k 0.00k/s) Relation(0 0.00/s)
Q: Is my computer too slow? Any method to speed up (without complexing too much hardware)?
