Github user keith-turner commented on a diff in the pull request: https://github.com/apache/accumulo/pull/244#discussion_r112786051 --- Diff: core/src/main/java/org/apache/accumulo/core/iterators/WrappingIterator.java --- @@ -58,21 +58,21 @@ protected void setSource(SortedKeyValueIterator<Key,Value> source) { public Key getTopKey() { if (seenSeek == false) throw new IllegalStateException("never been seeked"); - return getSource().getTopKey(); + return source.getTopKey(); --- End diff -- I experimented with making the VersioningIterator and Filter not call WrappingIterator.getSource() multiple times in their loops. I saw a noticeable difference, like 5% increase for the VersioningIterator. I change the code to call getSource() once before the loop and store the source in a local var.
