Remko Popma updated LOG4J2-1607:
--------------------------------
Comment: was deleted
(was: 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.
!InjectWithoutProperties.png!
5: context data has 5 elements
50: context data has 50 elements
500: context data has 500 elements
!InjectWithProperties.png!
Same as above, with 5 properties that need to be merged with the context data.

> 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.
