How do I find out if anything is missing? Just browsing the map in modRana? Jankratochvil's post seems to suggest that.

Just FYI, I have now completed the conversion of my 152,127 tiles. I used my ancient Pentium 4 laptop from 2004. I did not copy the tiles, just mounted the N900 and did the conversion there directly. It took about an hour, which seems consistent with beermad's post (200,000 tiles in ~75 minutes). Except that he used a much more powerful machine, suggesting that the CPU power is not the determining factor.

The resulting sqlite files take 444 MB, a bit more than the 407 MB my tiles used to take, but much less than 1.28 GB my tiles used to occupy on the disk, even with the smallest cluster size I managed to get (8 KB). In other words, a huge improvement.
