      Description

      We have observed severe performance regressions through the touch counters introduced in https://github.com/SYSTAP/bigdata/pull/230/commits. These regressions were introduced for loading data (as part of our geospatial benchmarks) as well as for query execution (see govtrack results for 2.0.0v4 and the associated govtrack regression analysis in our benchmark sheets).

      There's no good explanation for that other than that, by introducing the counters, methods become more complex and aren't any longer inlined.
