[Tile-serving] [osm2pgsql] Extremely slow database update (#128)

[jeffjanes]

If /data/nodes is not cached when you start out, and it is accessed in a random order by the import, then it will take forever to warm the cache with the contents of that file.  You can try to prewarm it by doing "cat /data/nodes|wc -c" first.
