sorry Mike, can't reproduce it.
actually writing is magnitudes faster than reading on my laptop. see

i also added a debug breakpoint at
com.vividsolutions.jump.util.FlexibleDateParser.parse(String s, boolean
lenient) and it isn't even called during saving as SHP.

Exporting a big dataset to shapefile (1 300 000 objets - around 225+115 Mb)
with version 1.15 lasted more than 20 minutes.
Most of the time is used by FlexibleDateParser.parse().
