Matt T. Proud 978acd4e96 Simplify time group optimizations. 
The old code performed well according to the benchmarks, but the
new code shaves 1/6th of the time off the original and with less
code.

Matt T. Proud 62b5d7ce20 Oops. 2013-03-21 18:08:46 +01:00
Matt T. Proud 1e0d740f2a Conditionalize LevelDB index retrievals. 
The LevelDB index retrievals could be repeated in a given operation
batch if multiple queued mutations affect the same (Label Name) singles
and (Label Name, Label Value) doubles.  This is wasteful and
inefficient, as a single retrieval suffices.  Thusly this commit
retrieves the canonical index mappings if the said mapping has not
been looked up in a given batch.
