Julius Volz f2b4067b7b Speedup and clean up operation optimization. 2013-06-20 03:01:13 +02:00
Julius Volz f2b48b8c4a Make getValuesAtIntervalOp consume all chunk data in one pass. 
This is mainly a small performance improvement, since we skip past the last
extracted time immediately if it was also the last sample in the chunk, instead
of trying to extract non-existent values before the chunk end again and again
and only gradually approaching the end of the chunk.

Julius Volz 71a3172abb Fix and optimize getValuesAtIntervalOp data extraction. 
- only the data extracted in the last loop iteration of ExtractSamples() was
  emitted as output
- if e.g. op interval < sample interval, there were situations where the same
  sample was added multiple times to the output

Matt T. Proud ceb6611957 Fix regression in subsequent range op. compactions. 
We have an anomaly whereby subsequent range operations fail to be
compacted into one single range operation.  This fixes such
behavior.

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.
