---------------------------------------

With two ingesters, and the native map, I'm seeing 140K k-v/sec.

> I thought that the continuous ingest test was going slower than it used to.  I was getting
about 20K k-v/sec on my desktop.
> After turning off the WALog, ingest shot up to 200K k-v/sec.  I expected some improvement,
but not an order of magnitude.
