>
> The indexing time for my ~2M documents has gone up significantly when I
> started adding fields of type NumericDocValuesField.
>
> Upon debugging found the bottleneck to be in the
> PerFieldMergeState#FilterFieldInfos constructor. The contains check in the
> below code snippet was the culprit.
> {code:java}
> this.filteredNames = new HashSet<>(filterFields);
> this.filtered = new ArrayList<>(filterFields.size());
> for (FieldInfo fi : src) {
> if (filterFields.contains(fi.name)) {
> {code}
> A simple change as below seems to have fixed my issue
> {code:java}
> this.filteredNames = new HashSet<>(filterFields);
> this.filtered = new ArrayList<>(filterFields.size());
> for (FieldInfo fi : src) {
> if (this.filteredNames.contains(fi.name)) {
> {code}
