Julius Volz 86fc13a52e Convert metric.Values to slice of values. ... The initial impetus for this was that it made unmarshalling sample values much faster.

Some of the smaller append examples take minimally longer, but the cost seems to get amortized over larger appends, so I'm not worried about these. Also, we're currently not bottlenecked on the write path and have plenty of other optimizations available in that area if it becomes necessary. Memory allocations during appends don't change measurably at all. Change-Id: I7dc7394edea09506976765551f35b138518db9e8		12 years ago
