I am using the REST API to retrieve results in csv form. Now, when I get the page_data.csv, the DNS lookup times are missing. Similarly under results.csv the DNS lookup time (#48) is missing. Any way to turn these back on ?
Do you have an example? If you're looking at Chrome the DNS (and socket connect times) are in a new set of columns at the end because the old schema couldn't support the fact that the DNS lookups and socket connections can happen disconnected from the actual requests (Chrome has a look-ahead prefetch algorithm to set up connections before they are needed).
