> The new {{StripedStatisticsImpl}} uses {{LongAdder}} and {{DoubleAdder}}, which are not
optimized for setting specific values like one would with a gauge type statistic. As such,
{{StripedStatisticsImpl}} has to synchronize set and get operations to avoid races. Consider
optimization that uses {{AtomicLong}} or well suited structure.
