Is there a simple way to count number of features returned by IMapServer3 object

Using the arcobjects SDK (10.7.1) I am simply trying to count the number of features returned by a feature service query, here is some sample code:

IMapServer3 ms = (IMapServer3) this.mapServerDataAccess;

...

// query for relevant features using spatial filter
QueryResult queryResult = (QueryResult) ms.queryData(mapName,
getTableDescription(mapServerInfo, layerId),
spatialFilter, qResultOptions);
RecordSet rs = (RecordSet) queryResult.getObject();

I can count the number of features returned by getting a cursor and iterating through the cursor items incrementing a counter along the way but this is extremely slow and when working with layers with 2+ million points this is not feasable. Is there a way of getting the count of the number of features in the returned RecordSet? I couldn't see anything obvious.

Appreciate your help.

If you use a IRecordSet2 class, it has the Table property. You should be able to use the ITable's RowCount method.
