What's the current status?  On Thursday August 31, some changes 
were made to the tile renderer, I guess it was the SQL.  Database 
load went down and tile generation throughput went up.  The slippy 
map showed only white thin lines, but was pretty fast.  Perhaps 
more important, I didn't see any all-white tiles and none where 
streets were missing.

Since yesterday Monday September 4, the slippy map has colors 
again, and is very slow again, still right now.  Is the slowness 
because of the changes that also brought back the colors, or 
because of your (ongoing?) backup?  Together with the current 
slowness, I'm again seeing plenty of all-white tiles and tiles 
where streets are missing.  It's starting to look like my terrible 
screenshot from August 27,

I really like the colors, but I prefer speed even more.  And I 
totally hate the broken tiles.

Do we have any logs from which we can compile statistics on how 
often the tiles get broken?  Or are we acting as if it just 
doesn't matter?
