Actually, the instructions I was following called for -C 2048
(http://weait.com/content/build-your-own-openstreetmap-server), but when
I did that I got the following error (running in a 4GB Ubuntu 10.04 VM):
> Out of memory for dense node cache, reduce --cache size
I had to reduce to -C 1800 to make it even run. Nodes imported nice and
fast (43.6k/s), but I received the following error:
> Out of order node 244067335 (33792779,7) - this will impact the cache
> efficiency
which to my novice reading implies that there was an issue in the Planet
file dealing with node ordering. And the Way import is running MUCH
slower than I would have thought given what I've read. 0.12k/s is WAY
less than 43.6k/s. I know ways are slower, but I figured maybe 10% of
the speed worst case, not this much slower.

PS. I haven't seen a -C 12000 recommended anywhere. And interestingly
with -C 2048 complaining , -C 1800 is still only using 2GB of the 3.7GB
available according to Ubuntu's System Monitor.
