--------------------------------------------------------------
When I ran the JMH ThreadContextBenchmark I found a performance problem when
merging context data with properties. This is now addressed. Updated benchmark
results follow below.

> for LOG4J2-1349 showed that the SortedArray-based data structure can be
> copied fast, but its {{get()}} and {{put()}} performance is worse than a
> hash-based data structure like the JDK HashMap.
> This ticket is to investigate options for improving performance of the
> {{get()}} operation, since this can impact the performance of Filters and
> Lookups.
