Suggestions for improving DataFrame row iteration speed

Jan 17, 2014 at 6:26 AM
The current implementation of DataFrameRow as of 1.5.5 makes the row-wise iteration through a DataFrame extremely slow.How about storing the row's values as a IDictionary<string, object> instead of trying to get the indexed element from DynamicVector out of its parent DataFrame each time the row's "cell" is accessed, which seems to be too slow.
