Irregular variation in conversion duration #45

@jalisdairi I converted WellLog observations tonight from WFS to GeoJSON and what's interesting is that there isn't any clear correlation between how big a WFS response is and how long it takes to convert to GeoJSON.

For example:

WFS GetFeature Size Time to convert
TX WellLog 242 MB 337 seconds
WV WellLog 30 MB 182 seconds
NY WellLog 73 MB 109 seconds
IL WellLog 204 MB 1,879 seconds
DE WellLog 178 MB 1,641 seconds
KS WellLog 362 MB 3,665 seconds (that's an hour)

The long ones get backed up and are the last to finish. It makes you think something hung because the log doesn't report anything for like 30 min.

I don't understand why the big difference in times though. Its almost like ogr2ogr gets tired.
